Thank you sir for the video and review. Watching it had me add dishpans under my canisters which saved the day. Had a little too much media in one and had a small leak, discovered next day and pan had 1.5” of water in it and not on my wood floors. Thank you again.
One little tip I would like to add, if you are having a hard time uncurling your tube, run hot water over it and it makes the hose easier to work with.
Hi Jason, I have the same filter and it has worked flawlessly for over a year now. It's set up exactly as the pondguru sets his up. Course, medium and fine reticulated foam that he states and split the extra fine pad that came with the filter all in the bottom basket. 3 kilos of Biohome ultimate in the top two baskets. Lava rock will work great also but would take longer to cycle. I would recommend filling the baskets completely with foams and bio media. I have a smaller Sun Sun canister without a pump daisy chained on the intake hose that's filled with foams only and I put a purigen bag in top of the smaller canister. The smaller canister catches most of the detritus and really makes a difference. I service the large canister twice a year and it's not that dirty. The smaller canister is easier to service and this set up works best for me. I've noticed every time I service either filter air will get trapped in the system. Rocking both filters left, right, back and forth has worked for me. Make sure the o-rings are in good shape and not dried out. Your tank looks awesome and very clean. Good luck.
beerstore415 I have a turtle and aome fish in a 15 gallon tank. I have a filter but I feel the water could and should be more clear. Should I get rhis filter? Kinda new to it and watched a ton of videos but you seem to know what you are talking about :D
beerstore415 hey I have set up similar setup.. Top two trays 1.5 Litre of Seachem Matrix, Bottom tray has Ceramic Noodles, daisy chained HW 603 filled with foam.. bit I feel the water flow is no way near 1000 L/Hr ... It could be around some 300 to 400 L/H.. how is Ur experience
you reminded me I hadn't cleaned my filter in several monthes. I broke it down and it was dirty, but I have seen it worse. I fill the bottom tray with mechanical media then bio in the rest.
From bottom up... you should use coarse/medium foam for the first filtration layer, bio media for the second, then the filter floss on top. Filter floss clogs pretty easily and that's why it should be at the top, and the coarse/medium foam at the bottom.
good tips. the smaller tubing help us who have a 5 foot column tank on a 3 1/2 foot stand. less water flow less stress on the pump. although your filtering nearly twoce the water. keep your sponges on top when doing quick changes, easier to get to.
You modeled your intake off of the spray bar. To have better draw from the bottom of the tank you should have a single opening or perforated/slotted opening on the last say 1 1/2" of the intake. And I would recommend adding a pre filter sponge to avoid fry being pulled in and it adds additional mechanical and bio filtration. Besides that, nice video.
I have a marineland c220 canister filter. Found that if the hose are not cut square and all the way to the threads when you tighten the plastic nuts. Air tends to be suck through the canister.
The filter intake is fed by gravity, putting it higher makes it perform less efficiently because you're slowing down the filling of the filter so its getting air in because its pulling water out faster than its filling.
Hi Jason, thanks for the excellent video and explanation. I have the same sunsun 303B and experience the bubbles getting blown out despite removing all the air bubbles and ensuring no leaks. Mine is on the floor below the tank level and still blows air so I don't think the filter level could be the issue. Also the longer it runs the more air it seems to blow out so I presume maybe the bacteria in the bio media could be producing gases, unless the intake outlet fitting is allowing air in.
It's sad to see how so many people think this is a gravity thing and it has to be on the floor. It only has to be below the top water level. We can't escape physics, the return tube negates their "gravity" theory... I enjoyed this video 🙂
I had one of these 304B at about 6 months i started having problems th uv bulb melted the media baskets, it got leaky, the media it comes with is crap plain said, even after 2 weeks it was filthy inside like the walls & trays,the media dont seem to hold the waste,so after spending 30.00 on new media it got better,its loud.i finally got a fluval 306 its 3Times the filter the sunsun is ...its so quiet silent.. the tank has a crystal clear look to it it never had with the sunsun,matience is a breeze,great media i add 1 pouch of chemi pure its been over a year and the 306 is like the day i got it great filter.. just my review you really get what you pay for in a canister filter
Susanne Ayotte you don’t have to rock it to get air out if you put it under the aquarium like it’s suppose to be. The Siphon isn’t keeping up with the flow. That’s why it’s getting air. With it under the tank gravity will work and make it easier on the pump and siphon and you won’t have the air problem. He doesn’t have his set up right. That’s why.
The air in your filter is due to cavitation, because the return line is less restricted than the out take coming from the tank. Reverse your hoses. And in addition, having the filter lower will increase the ability to siphon water out of the tank. Canister filters are primarily gravity fed and the pump is to return the water, not suction it the way that a HOB filter does.
Im planning on buying one of these filters, i saw you said the return piping sucks, good thing i ordered some ada glass return and glass inflow. Not so cheap but worth it
The filter is making that noise because it is having difficulty in siphoning the water as it is kept at the same level of the aquarium. Further, the intake pipe is far away from the filter making it even harder to pull the water.
It is not recommended to Vaseline seals of filters, despite it being popular in the hobby. Overtime that actually increases your chances of the filter leaking. It is actually recommended to use silicone grease/oil. Also, I don't get why you have an empty tray in your filter in the first place? Why not do more lava rock or something else to maximize the use of the filter?
Thanks. Yes I would think so too and therefore have never used Vaseline. However, the other day I just happened to re-read the instructions on the box and the manufacturer has mentioned using Vaseline on the o rings.
I’m new to this hobby and just recently purchased the same model of filter. I haven’t used it yet because I want to use glass lily pipe set for water intake and outake. My concern is the size of the hose. Will any glass pipe fit with that size?
I would use a different intake design as you want adequate flow direction which requires the intake to be further down concentrated close to the substrate
I'm having same problem with my 704b..after prime and rocking side to side to fet all air out. I'm still getting little micro bubbles..any fix for that?
Mine takes hours(sometimes 4-15 hrs or more) to actually start pumping water out. And when I siphon it, water ends up leaking from outside of the filter. Any suggestions?
I uave this pump wiith all three trays full carbon, sponge,filter rocks on my 6x2x2 does brilliant but the flow is a work in progress to do the whole tank maby a water fan will do
NPORT1981 That is the one I own and I have put miles on it! Shut it down for a few years pulled it out again and cranked her back up still seals great and is currently filtering my reef tank as a Bio media canister only in tandem with a fluval 406 that does the mechanical and chemical only together I have excellent filtration. I bought this filter from True Aqua online for 150 bucks to my door canadian and have said always the best 150 I have ever spent! The aquatop CF 500 UV filter 525 gallons with media is lower than that but this filter is a beast I had it on a 66 gallon, now is running 63 gallon reef aquarium. And I will soon referbish it with new trays and a light because I love this filter that much!.
JDO Fishtank a lot of incorrect information and that's NOT the intake with all the holes Sir... but SUNSUN IS A GREAT canister filter if you use it below the fish tank and correctly.
If you watched the video I added a caption correcting myself on the intake, so what else am I wrong about? And if you watched my later videos you'll see I moved the canister under the tank? Take your foot out of your mouth?
I would also recommend switching the current configuration of your suction and discharge lines. The shorter the suction line the lesser pressure loss. Great review though, thank you sir.
It should make no difference! No matter where you put the filter the water reaches equilibrium in the two hoses. The extra velocity of having the filter lower will be canceled out by the extra head height of pumping higher..
You know what? I really do LOVE both of my sun sun 304B's..and I did the same thing on my out put tube..the water flow is much better..BUT....The only thingI hate about my sun sun is that whenever I have to move ..like I just relocated in another city and I swear to you I have sooooo much trouble getting it to prime and I foloowed everyones advice on you tube!! It really gives me a hard time but only on one of my sun sun filter systems..Btw..You can make your own outputs with PVC pipe and drill holes in it...but I guess $7 aint bad..I like yours where did u buy that? Oh your tank is very clean good job!!
Another trick with the curled hoses. Use a hair dryer on heat to soften the hose, then lay them out straight. Let it cool completely... do this a couple times and it will "memory" the straight shape.
I have had the same problem with the same filer, sucking in air some where? It's been up running for over 6 month's and still on a daily basis spits out big pockets of air. I rock it back and forth, front to back, all air comes out but continuously keep spitting out trapped air. Can anyone help me out what may be the problem. Thank you.
Hii, Thank you for the video. I have a situation, I got 14 Frontosa of size 7cms in my 200lt 4ft standard tank. Will this filter be the best or no? Or which would be the ideal for my situation as they are going to grow bigger 25cms approx. Please advice. Thank you very much,
I have same filter from amazon India and my tank is about 300 litres or something so sometimes I feel like my filter is not strong enough to suck all the particles inside so is there any chance if I could make it more powerful thanks
Once the water starts to flow on its own the thing will re-prime itself even if the canister has been opened for maintenance. The trick is once the return lines have been filled, the syphon remains "locked" in the system. Although you have explained that the ridgid tubing that comes with the filter is undesirable, I have noticed that you replaced the brackets that holds both hoses securely to the aquarium with suction cups. I just hope for your well being that The suction doesn't ever break.... I just finished setting up my HW- 303B and honestly, I don't find anything really bad about the hardware parts of the filter. Even the suction cups that holds both tubes in place have a decent suction to them. I do like the idea of using just a 90° aftermarket PVC push-on fitting for the return line though. I was never a fan of spray bars as they seem to clog up some how. I have searched Amazon's website for an alternative hose clamp bracket and came across the Fluval mounting bracket used for their canister filter systems. They're really reliable and trustworthy as far as keeping the hoses in place. Just suggestion!
I got a sun sun hw-302 second hand. Primed it and water started leaking out around the four grey latches. I’m guessing the o-ring needs to be replaced? Has anyone else experienced this issue with the sun sun? How often should we replace the o-ring?
I have the cf 500 uv filter which is a four stage filter and it has run like a champ for years I am using it on a reef tank at the moment and with over 5 solid years it has never leaked although the trays for the media are wearing out with debris passing through them this is my only complaint but I have miles on this filter! Simple tough and having a uv bulb to help with issues is a great feature! The flow is killer I have no complaints other than wear and tear on the trays they do disintigrate over time.
You may need to rock it in different direction when you start to up to remove all the air in the filter. When you no longer here the air you are all set.
what kind of lights do you use on that tank? It looks super nice. I'm pretty sure I'm going to get the sunsun 704b for my 75 gal ac tank. great video, very informative.
I would like to know how you did that flow test. I have bought 5 of the larger version of this filter 4 HW-304b's and 1 HW-404 they are on much bigger tanks and work fine using the included plumbing and fittings. There is a reason they use that smaller tubing. I doubt yours is actually sucking air, it takes a while to bleed all the air out of these filters.
Bass Player With the way he sounds and the way he’s set this filter up, I’d guarantee you he’s never tested anything and probably don’t know how to test it. Lol.
Hey they make the tubing green that's because that is the only color that plants and Algae can't use to consume the right color spectrum to grow. A very big plus if you have Algae problems.
The solution of your air problem, if you haven't figured it out yet, is your canister had to below the tank. It is a gravity feed.. Definitely needs to sit below the intake at the very least. BTW, companies rate their filters with no media or sponges loaded.
Thanks for the review, I just ordered a 304b. Any chance you have an idea what parts you used plumbing wise for the intake and output? Do you recommend making a spray bar for output? Thanks!
Watch some of my updates on this tank, it shows what I made. I ended up using the spray bar but I have it in the tank vertically so it's spraying an even amount of filtered water from the bottom to the top of the tank.
JDO's Fishtank thanks I just watched all of your videos pertaining. Everything looks great. Sorry I guess I was looking for several type of parts lost. When mine comes in I can bring a hose to home Depot and check. Thanks, now I know parts that come with aren't great.
how do you know what the pump is pushing out from rated 250gph add longer hose and you're like it goes down to 180gph then add media and goes lower. Do you have a electronic meter to register actual pump flow? Or just guessing?
i have this filter i use a different uv light though each tray has something in it filter pad with media tubes, amonia remover next tray,of course charcoal , media balls ive had it now 3 months filters really well for a 36 bowfront nothing huge ive changed filter once so far ...when i bought this from amazon i also purchased 12 filter pads that work in it..kinda a bundle deal that amazon suggests what to get with total cost was 85$ not to bad decent filter so far next step diatom polisher. its gotta be below your tank though thats part of how they operate just a heads up
the problem is the canister needs to sit lower. the siphon is not keeping up with the pump flow. ive had something similar happen to mine before. also the smaller oulet tubing would provide more pressure to circulate the tank as long as its not too small that it creates back pressure on the pump. with the floss tray i would add a sponge before floss so floss doesnt clog up too easy. and it would also acts as a bio filter at the same time.
3 to 4 ft below it would be just fine. It would be better then setting it right beside the tank like he’s doing in the video. All my stuff goes in the cabinet under the aquarium.
Looks like an old video, I’m sure you changed this setup by now fixing the install issue. Canisters must be below the intake/over flow. Must move this below your tank, not an option.

Pond guru is right on the money all the time!
Just plain logic
How do you prime to smaller daisy-chained filter man?
Have you tried soaking the hoses in warm/hot water for a few seconds first? This makes the hoses soft and easy to accept a new shape.
thats not a intake pipe its a spray bar for the output :) that circulates the water gives good surface flow
I stand corrected, it's still junk.
I added a caption saying it wasn't the intake, thanks.
ok cool glad to help out
Still that doesn't change flow, simple fluid dynamics, only velocity changes not the volume...
Aditya A. Aima glad I'm not the only one upset by him saying that
you reminded me I hadn't cleaned my filter in several monthes. I broke it down and it was dirty, but I have seen it worse. I fill the bottom tray with mechanical media then bio in the rest.
thx for showing how to improve the water flow with the bigger outflow fitting
Love the parents with the fry , should have seen more of this!
From bottom up... you should use coarse/medium foam for the first filtration layer, bio media for the second, then the filter floss on top. Filter floss clogs pretty easily and that's why it should be at the top, and the coarse/medium foam at the bottom.
Yeah he has it wrong and empty canister is a waste
Great vid…I got the 304b running on a 100 gal tank.. Still working out the kinks…Good video….👍🏾
sunsun the best
good tips.
the smaller tubing help us who have a 5 foot column tank on a 3 1/2 foot stand.
less water flow less stress on the pump. although your filtering nearly twoce the water.
keep your sponges on top when doing quick changes, easier to get to.
Best unboxing video.
Just bought one of these, never had a canister filter, always had HOB’s. Didn’t know if I put it together correctly. This helps a great deal.
Put it on the floor
You modeled your intake off of the spray bar. To have better draw from the bottom of the tank you should have a single opening or perforated/slotted opening on the last say 1 1/2" of the intake. And I would recommend adding a pre filter sponge to avoid fry being pulled in and it adds additional mechanical and bio filtration. Besides that, nice video.
Thanks
thanks for the video man! it’s informative and interesting. u should make another one!
It’s Ralph thanks, I do, some of my newest ones
I have a marineland c220 canister filter. Found that if the hose are not cut square and all the way to the threads when you tighten the plastic nuts. Air tends to be suck through the canister.
Bro good vedio, it was completely honest. People needs youtubers like you.
Yethu Raj thanks!
I have the sun sun HW-302 and I like it very much. So much I ordered a sun sun 304b that I will use on my 75 gallon tank
George A. Williams Sr. Awesome

Why do you just leave an empty tray you should put some carbon in there or something
I had one of these 304B at about 6 months i started having problems th uv bulb melted the media baskets, it got leaky, the media it comes with is crap plain said, even after 2 weeks it was filthy inside like the walls & trays,the media dont seem to hold the waste,so after spending 30.00 on new media it got better,its loud.i finally got a fluval 306 its 3Times the filter the sunsun is ...its so quiet silent.. the tank has a crystal clear look to it it never had with the sunsun,matience is a breeze,great media i add 1 pouch of chemi pure its been over a year and the 306 is like the day i got it great filter..
just my review you really get what you pay for in a canister filter
Glad it worked out for you
There you go. I commented before I saw you rocking it.
Susanne Ayotte you don’t have to rock it to get air out if you put it under the aquarium like it’s suppose to be. The Siphon isn’t keeping up with the flow. That’s why it’s getting air.

I like your intake customized one
Any video there how you made it!??
Entire vertical holes I like it very much
Im planning on buying one of these filters, i saw you said the return piping sucks, good thing i ordered some ada glass return and glass inflow. Not so cheap but worth it
The filter is making that noise because it is having difficulty in siphoning the water as it is kept at the same level of the aquarium. Further, the intake pipe is far away from the filter making it even harder to pull the water.
if it were me I'd prob switch the two hoses lol
Should you use a towel when changing or cleaning these filters in the Kitchen?
And if not should you bleach your counter afterward?
It is not recommended to Vaseline seals of filters, despite it being popular in the hobby. Overtime that actually increases your chances of the filter leaking. It is actually recommended to use silicone grease/oil. Also, I don't get why you have an empty tray in your filter in the first place?

Vaseline will roin your gasket in time!!!! Use SILICONE. DAAAAAA
RUIN, SORRY
@@craigwoodhull3028 yep . Petrolium jelly. Might as well rinse them in gasoline
Thanks. Yes I would think so too and therefore have never used Vaseline. However, the other day I just happened to re-read the instructions on the box and the manufacturer has mentioned using Vaseline on the o rings.
love this video, didnt know that i can place the sunsun303b can fliter beside the tank.
barryscottfujiwara you can’t, don’t do it, I had issues doing that
JDO oh i see , what happened?
so u tranferred it?
barryscottfujiwara has to be on the floor for it to work properly
I’m new to this hobby and just recently purchased the same model of filter. I haven’t used it yet because I want to use glass lily pipe set for water intake and outake. My concern is the size of the hose. Will any glass pipe fit with that size?

Very informative video. Thanks for sharing and as always do what you do if it works for you.
I had the same canister filter for years every time I clean mine I put brand new filter pads in there I never reused them?
I'm having same problem with my 704b..after prime and rocking side to side to fet all air out. I'm still getting little micro bubbles..any fix for that?
You should have some fine media in that top basket so the water going back into the tank is clean as possible
I do now. I filled up both baskets with lava rock, but that doesn't filter the water for debris, the filter floss does that.
Mine takes hours(sometimes 4-15 hrs or more) to actually start pumping water out. And when I siphon it, water ends up leaking from outside of the filter. Any suggestions?
I uave this pump wiith all three trays full carbon, sponge,filter rocks on my 6x2x2 does brilliant but the flow is a work in progress to do the whole tank maby a water fan will do
hi, why are the filter baskets partially empty ?
can you please tell me how put the two hinges that come off . I can't figure out how to put the back on please some one help
@JDO have u thought about using a lily pipes?
Can I use this for 75 gallon tank ?
Been eyeing the 525gph canister filter for a while. If quality is decent, the price is unbeatable.
NPORT1981 That is the one I own and I have put miles on it! Shut it down for a few years pulled it out again and cranked her back up still seals great and is currently filtering my reef tank as a Bio media canister only in tandem with a fluval 406 that does the mechanical and chemical only together I have excellent filtration.

Thank you. Links to your hoses and fittings would be very helpful.
Do they make canister filters for 25 gallon tanks? I know usually the bigger the filter the better but would it be too much for a 25?
You make the pump work extra hard by not putting the canister below the tank. It does use a siphon effect in conjunction with the pump.
You are correct, I moved it under the tank, watch one of my later videos
JDO Fishtank a lot of incorrect information and that's NOT the intake with all the holes Sir... but SUNSUN IS A GREAT canister filter if you use it below the fish tank and correctly.
If you watched the video I added a caption correcting myself on the intake, so what else am I wrong about? And if you watched my later videos you'll see I moved the canister under the tank? Take your foot out of your mouth?

The extra velocity of having the filter lower will be canceled out by the extra head height of pumping higher..
You know what? I really do LOVE both of my sun sun 304B's..and I did the same thing on my out put tube..the water flow is much better..BUT....The only thingI hate about my sun sun is that whenever I have to move ..like I just relocated in another city and I swear to you I have sooooo much trouble getting it to prime and I foloowed everyones advice on you tube!! It really gives me a hard time but only on one of my sun sun filter systems..Btw..You can make your own outputs with PVC pipe and drill holes in it...but I guess $7 aint bad..I like yours where did u buy that? Oh your tank is very clean good job!!
Another trick with the curled hoses. Use a hair dryer on heat to soften the hose, then lay them out straight. Let it cool completely... do this a couple times and it will "memory" the straight shape.
Worth watching, thanks
Learners' Tank no problem
thanks for this information
I have had the same problem with the same filer, sucking in air some where? It's been up running for over 6 month's and still on a daily basis spits out big pockets of air. I rock it back and forth, front to back, all air comes out but continuously keep spitting out trapped air. Can anyone help me out what may be the problem. Thank you.
TY we tipped our new one and got a lot of air out of it.
the spray bar is good for aeration give me a good ol Eheim anytime
How quiet? I am looking for a quiet one my new one keeping me awake at night.
Hii,
Thank you for the video.
I have a situation, I got 14 Frontosa of size 7cms in my 200lt 4ft standard tank. Will this filter be the best or no?
Or which would be the ideal for my situation as they are going to grow bigger 25cms approx.
Please advice.
Thank you very much,
I have same filter from amazon India and my tank is about 300 litres or something so sometimes I feel like my filter is not strong enough to suck all the particles inside so is there any chance if I could make it more powerful thanks
I think there great filters I got a name brand cost 4x the amount and both tanks look great. I swear by them
I don't agree with the way you have the filter stages setup but other than that good video!
The UV light in my filter has been doing it's job for 24/7 365 for 3 years and still going strong.....QUICK KNOCK ON WOOD HEHEHE=)
Hello how do I get the uv light to work I too it apart and the uv light is not showing but its on

Someone told if u keep ur canister filter off for a day or two it gets infected, instead have to keep Running. IS IT TRUE???
Sir is it Nessesary to put uv light 24 / 7 or can put for hourly basis in 4ft koi tank.
Yo the small output fitting is ment to jet the water for more and better surface ripple for more oxygen
I got a sun sun hw-302 second hand. Primed it and water started leaking out around the four grey latches. I’m guessing the o-ring needs to be replaced? Has anyone else experienced this issue with the sun sun? How often should we replace the o-ring?
John Da Silva haven’t had those issues. Check to make sure the top is on correctly, if it’s still leaking return it.
I can’t get mine to pump the air out I turn it on and doesn’t do anything?
Where did you buy the sucktion cups and the little piece that you add on it I don’t know how it calls
I have the cf 500 uv filter which is a four stage filter and it has run like a champ for years I am using it on a reef tank at the moment and with over 5 solid years it has never leaked although the trays for the media are wearing out with debris passing through them this is my only complaint but I have miles on this filter! Simple tough and having a uv bulb to help with issues is a great feature! The flow is killer I have no complaints other than wear and tear on the trays they do disintigrate over time.
how do you work out what the flow rate is
how often do u need to clean the filter ?
You may need to rock it in different direction when you start to up to remove all the air in the filter. When you no longer here the air you are all set.
Can anyone tell me the size of tube pipe for hw-303b tank?thanks in advance
what kind of lights do you use on that tank? It looks super nice. I'm pretty sure I'm going to get the sunsun 704b for my 75 gal ac tank. great video, very informative.
It's a Beanswork led fullspec light, I did a video on that.
I would like to know how you did that flow test. I have bought 5 of the larger version of this filter 4 HW-304b's and 1 HW-404 they are on much bigger tanks and work fine using the included plumbing and fittings. There is a reason they use that smaller tubing.
I doubt yours is actually sucking air, it takes a while to bleed all the air out of these filters.
Bass Player With the way he sounds and the way he’s set this filter up, I’d guarantee you he’s never tested anything and probably don’t know how to test it. Lol.
I have the exact same filter but on the floor, the flow is much greater than in this ''example''.
Hey they make the tubing green that's because that is the only color that plants and Algae can't use to consume the right color spectrum to grow. A very big plus if you have Algae problems.
The solution of your air problem, if you haven't figured it out yet, is your canister had to below the tank. It is a gravity feed.. Definitely needs to sit below the intake at the very least. BTW, companies rate their filters with no media or sponges loaded.
I was hoping to see how you change the UV light?
How is the built quality !?? Should I got for uv or without uv!??
What is the name of this intake water pipe which u bought,
16:40 and 19:40 how can I make those ? BC I need them bad 😭
Thanks for the review, I just ordered a 304b. Any chance you have an idea what parts you used plumbing wise for the intake and output? Do you recommend making a spray bar for output? Thanks!
Watch some of my updates on this tank, it shows what I made. I ended up using the spray bar but I have it in the tank vertically so it's spraying an even amount of filtered water from the bottom to the top of the tank.
JDO's Fishtank thanks I just watched all of your videos pertaining. Everything looks great. Sorry I guess I was looking for several type of parts lost. When mine comes in I can bring a hose to home Depot and check. Thanks, now I know parts that come with aren't great.
how do you know what the pump is pushing out from rated 250gph add longer hose and you're like it goes down to 180gph then add media and goes lower. Do you have a electronic meter to register actual pump flow? Or just guessing?
I had the return shoot the water into a gallon jug and timed it. Get it?
Greetings....I have the sunsun 704b and a 25 gallon cube aquarium...it will be a lot of filtration, or it can be used.
is this canister filter good for 3OL×18B×18H aqaurium? reply plz
cool vid I just brought one of these myself
Thanks, I like it a lot.
any water leakage yet? heard many negative reviews about its leakage problem
How long I can use without cleaning ?
i have this filter i use a different uv light though each tray has something in it filter pad with media tubes, amonia remover next tray,of course charcoal , media balls ive had it now 3 months filters really well for a 36 bowfront nothing huge ive changed filter once so far ...when i bought this from amazon i also purchased 12 filter pads that work in it..kinda a bundle deal that amazon suggests what to get with total cost was 85$ not to bad decent filter so far next step diatom polisher. its gotta be below your tank though thats part of how they operate just a heads up
Thank you
Try doing a review after 18th months to let us know how long the filter lasts. Thanks.
the problem is the canister needs to sit lower. the siphon is not keeping up with the pump flow. ive had something similar happen to mine before. also the smaller oulet tubing would provide more pressure to circulate the tank as long as its not too small that it creates back pressure on the pump. with the floss tray i would add a sponge before floss so floss doesnt clog up too easy. and it would also acts as a bio filter at the same time.
minhng90 Do you think that this pump would be okay sitting about 3 or 4 feet below the aquarium? Or would that be too much for it to handle?
3 to 4 ft below it would be just fine. It would be better then setting it right beside the tank like he’s doing in the video. All my stuff goes in the cabinet under the aquarium.
What the pipe sizes for the intake and output ?
Nice tips on the canister
Looks like an old video, I’m sure you changed this setup by now fixing the install issue. Canisters must be below the intake/over flow. Must move this below your tank, not an option.
Yes, that’s the whole concept of syphoning
Sir if this filter good for a 4 feet 18 tall 18 trench tank
what is the purpose of the empty tray? why not put more lava rock or such in it?
agree . thanks
What did you buy for the parts on the tubes sizes and such
