I’m really glad you have this video up still after making a new diy co2 video, I find the instructions a bit more clear in this one and you might have been nervous but I think you did great explaining things. Both videos are very helpful and appreciated.
@@MJAquascaping followed the video and a DIY diffuser video and it’s working like a charm. The diffuser is made using a chopstick cut down into a reed basically. Thanks again 👍
I used this method but even after 1 days and 5 hours still no bubbles are forming ,i used blueberry syrup mix instead of gelatine and air stone instead of diffuser can you help ,by the way love your videos
@@vikalawa5301 I think gelatin is important to his method to slow down the sugar consumption so the yeast doesn’t choke itself out producing too much alcohol too quickly. Is there any pressure buildup so far? That would at least let you know something is halfway working. If there isn’t any pressure and the bottle squeezes easily then there may be a hole somewhere in the cap/line that needs to be glued better, or the lid of the bottle may have something on it preventing a good seal.
Not clear on instructions but what it looks to me is Single line going into first bottle (REACTOR) 1" down from cap and water level 3" below top of bottle.Second bottle(the wash) FIRST hose coming from reactor 6"-8" long going down into bottle. SECOND hose to check valve going into bottle 1" from cap then water level 2"-3" below top of cap. Thanks for the video great info
Brilliant video. Tried this. Edit/Update: ok so my actual hose had a tiny hole in it!!! Replaced it and working like a bomb ❤ "The bubble are working. But nothing comes out of my diffuser. There' are no leaks and bought the correct diffuser many have used on dyi co2 systems. Maybe my house is just too cold."
That gelatine sounds like a nice improvement. I was using a mixture without it when I had bio CO_2 system on my fish tanks, otherwise it was basically the same (even the same dry yeast). Don't use silicone, it won't take a hold. Epoxy could work, but I was using electrical tape and a piece of tubing (from inside) to get rid of any leaks on the cap. I heard it can be tweaked further with special yeast, such as used for wine or "hard liquor basis" which last longer as they can stand higher alcohol levels.
The silicone caulking should be put on the inside of the cap, not the outside. It will hold the pressure up to rupture of the bottle (approx 100-150psi).
Thanks for your video. It’s very clear and looks easy. What are the bottles you “pre-made” ? Water-gelatine-sugar? Or the whole mix including the yeast ?
Thanks for the video! I have a question, when you said to prepare new bottles ahead. It means that you only make the sugar+gelatin mix, then add yeast later when you swap out bottle right? Thanks!
I have setup this system now. I just keep Jelatine sugar water refriragtor only 7-8 hours. After make mixture, 6-8hours later CO2 realised. I use passive CO2 bell. I hope this work for my plants. Thanks
OMG. This is perfect, I am just going to combine my Kombucha/ Beer making hobby with my new Aquascape hobby. I'll just have the one-way release valve from my fermentation project go to my fish tank!
Just uploaded a new video about diy CO2 😬 it’s very similar, just a better quality. And yeah the second bottle stops yeast from getting out of the diffuser 😊
Awesome Video. I made my DIY Co2 and it works. I'm about to add a valve when I finish my 1st bottle to see if we can regulate the amount of Co2 and shut it down at night.
I know this is an old comment but just in case anyone else sees this do not try to shut it off at night, the bottle will explode, if your worried just run an air stone on a timer at night to maintain oxygen levels
hell yah, i am going to try this on my 75G tank as soon as i get on days off. on the fence about a professional CO2 setup so this will give me a pretty good idea if i actually wanna use CO2 or not! i wonder tho, could i not just double all the ingredients and through everything in a 2ltr bottle? twice the capacity, same ingredients, maybe could get 8 weeks instead of a monthly swap?
Thank you very much for this video. I just made it but I have one question, if you or your viewers could help: I just saw a similar recipe, but instead of gelatin, they added baking soda? Is the process very different or similar? Thank you! Regards from Portugal!
I never knew about this. I’m definitely going to try it out. I bought a Fluval co2 kit and hate it so I’ve been doing more research after that experience. Really wishing I bypassed the kit and just bought the equipment all separately. But this diy system will be fun to try. Learning a lot from your channel. Thanks so much!
Which Fluval CO2 kit did U buy? Im interested to hear more of ur experience & I’ll be glad to hear your honest appraisal .. I wish I could afford to purchase an Fluval kit , even if only to discover I HATED it. What part of the kit didn’t you like or didn’t work for you? Would you be interested in selling it by any chance please? I look forward to you response & hope you consider selling to a n Aussie Nerdy noob fish girl ready to dive headfirst into Co2!! Cheers.
Do you let the system build up pressure before putting the diffuser in the water? Or will the system make enough pressure to push water out of the diffuser line? My DIY system is making a bubble every 3 seconds. I have a one-way valve on there. the diffuser is in place in the water. But the system doesn't seem to be pushing water out of the line. Or am I not waiting long enough, and it should be diffusing CO2 tomorrow?
Basically just clean the bottle with warm water, and then fill it with a new recipe. Also watch this video th-cam.com/video/OtpfltN15-8/w-d-xo.html&lc=Ugz9_HRzz3o70tOF6-d4AaABAg
What co2 diffuses you have used, because I am not able see any bubbles from the diffuser but I can see co2 bubbles from tube after removing the diffuser can you provide any suggestions
Hi thanks for ur informative video i tried that at home but failed there was leakage of gas through the cap how can i seal it tight though i put adhesive tapes
My dennerle 60l cube came I’m going to reuse my fluval canister filter even if it might be abit overkill I have it lying around definetly going to do this thanks for the video!
Awesome video. I have a 120 l tank with a external filter that have a flute out pipe and an oxigen bomb. Should i turn the oxigen pump off while i am using co2 ( daylight) and turn it on by night? Or can it be on all the time?
Hi I’d like to thank you for your thoughtfulness making this tutorial.it’s great to know this about this method.it saves wasting money on commercial products.and what a great idea the gelatine is. I also like the clumsy bits in the last part of your video.😂👍🇦🇺take care Robert
Great video. I just got a LED light and want to add co2 in my grow tent. Just curious though as to what the co2 ppm would be using only sugar and water vs adding geletine
Last question i hope. I did everything like you. More than 24h later i have no bubles coming out of the difuser. How many bubbles are supose to come out? One or two every hour or you can look anytime and see bubbles?
This depends a lot on the room temperature, but in general I would say 1 bubble per 4-5 seconds. When you try to squeeze the bottle do you feel pressure? Or can you easily squeeze it?
I made one of these systems this week and I was getting no pressure. The diffuser was just a tank decoration. The system was pushing a bubble a second. I tried various diffuser options and was getting no bubbles. Today I checked the whole line system and found a small leak. Remade the line system, pressure and bubbles with glass diffuser was instant with the newly sealed system. I nearly gave up with this system. But I am a bit of a stubborn git, so rechecked everything, and boom, fixed. Now watchinh little bubbles flooding my tank.
Nope that wouldn't work well or maybe not work at all as it will either produce very large bubbles or might not produce at all as it requires high pressure to produce bubbles
Thanks so much for this tutorial! I'm going to do it on my small tank (paid for a CO2 kit for the main tank like a sucker). PS You're very nice to look at. 😉
Hi. You mentioned that by adding gelatin, it is good for smaller tank because the amount of CO2 is regulated/controlled. Does that mean if I have bigger tank, say 80 gallon, it is better to opt out using gelatin because bigger tank needs more CO2? I hope I get an answer. I would like to try this method. Thank you.
Yeah for a big tank like that it's probably better to skip the gelatin. Just know that without the gelatin the bottle won't last as long. You could also try to make a system with multiple bottles to give you more output.
@@MJAquascaping I also have another question. Is it necessary to make another bottle for "rinsing" or is it okay without it? Is the alcohol produced with CO2 harmful to my fishes? I'm sorry for asking so many questions. I'm new so I'm still fumbling. Your help will be appreciated though so thank you.
The rinsing bottle is not necessary :) The only thing that could happen is some ''yeast foam'' could get in the tubing and in the tank, but that's not harmful or anything.
Hi! You said that the system should not work during the night because of the lack of light. How do you manage your bottles? I saw some electronic valves that stop the CO2 during the night but that wouldn't make my bottle to build pressure and pop? I'm new to the planted tanks. I would really appriciate your help.
@@MJAquascaping I went yesterday out and got the tubing and an airstone. It's making small, fine bubbles. I will buy a proper diffuser later on. I was exited so I made mine at 2 am lol and when i got up around 7:30am already it was producing bubbles. It has a 1bubble/second rate. So far after 4h of pushing bubbles I do not see any problem with my big and baby guppies. I will keep an eye on them after i turn off the light for the first night. I moved the outlet of the filter so the water now is more wavey. Thanks for your awesome content and help!
Hi MJ. Are you experiencing any white slim on the diffuser. I have been using method and my diffuser gets clogged with this white slime/film. I have to clean it everyday to maintain fine bubbles. Any suggestion greatly appreciated
I just started watching a few of of videos on ur channel about diy n co2 I just joined I like ur channel n there's not a lot of aquarium channels I like now so keep up the good work
Hi Nathalie! Thank you 😊 No unfortunately that's not possible. If you would shut the system, the pressure would keep building up and i guess the bottle would explode 🤔 so although it is a very cheap solution, this is definitely the biggest downside.
If i make another spare of bottle with yeast just the night before i replace the old one, do i put the lid on fully so it wont “explode” or i leave it open without lid?
@@MJAquascaping hahahaha ya i was also thinking about that. Thank you. I made my first diy co2 following ur advise and it worked!! Haha now im making the second one for my bigger tank. Thank you 🙏
I prefer the diffusers with the brown ceramic disc, like the aquario, twinstar, dennerle etc. But tbh every diffuser will work as long as your system is completely sealed
@@MJAquascaping Thanks for reply. I had one of the glass diffusers from amazon, one of the cheaper ones.The diffuser had a good review. I run DIY kit with citric acid and baking soda.Its with gauge always showing nice pressure between 1.5 and 2 but for that diffuser I had to open the generator full and it was almost not making any bubbles.It was air tight. I think maybe it was faulty or maybe only suitable for very high pressure. I connected cheap small stone now and it's making very tiny bubbles which is really amazing for this type of stone I think it's a lucky stone, one in 1000.All the best MJ, waiting for more of Your videos.
since it cant be turned off,, is it ok i put that co2 24/7 in the tank with plants only (no livestock),, will it kill the plants since the co2 still inject the whole tank day and night?
The gelatin makes it more difficult for the yeast to consume the sugar, or basically they will consume it at a lower speed, this makes the system last a little longer.
Hi I've tried this system with my new diffuser and it needs alot of pressure to push bubbles through. How long does your system take to start diffusing bubbles into the tank? Thanks
How? Mine just won't work. Can't even find any leaks. Do you heat your house all year and never open windows etc. Mine only worked the first few hours (probably due to warm water and that extra tbs of sugar) and stopped. Now a bubble every 10+ minutes if I'm lucky and still not a single co2 bubble out of my diffuser.
I’m about to end my dry start. They say it’s best to have a lot of CO2 in the water at first when flooding the tank. Can this be done by adding less gelatine and or more yeast? Or keeping the bottle in a warmer place? Thanx in advance.
Yep more yeast will for sure speed things up! if you wanna go really crazy you can also leave the gelatine out. But both these things will reduce the longevity of the bottles, so you will have to replace them more often. (2-3 weeks)
Great video, I'm no Aquascaper but am learning a lot about how to keep an an aquarium from your vids. I had wondered whether it would be possible for cat owners to keep an open-top tank, as I will be bringing home a kitten in two weeks... Can you offer any advice on how to manage your cat's behaviour around aquariums please? 🌿🐠🌱🐟😺🌿
We have 2 cats, and they just love to drink from the tanks.. 😂 they don't care about the fish at all. So we just let them drink from it, there's no harm in that.
@@MJAquascaping now there's a picture, thanks Mark, it certainly gives me hope that both kitten and fish will be able to live together in harmony. I saw a video of a cat diving into a full tank the other day 😅, this is my first time owning pets, wish me luck! 🙂
@@sweetdreamstime2266 I have a cat and a fish tank that stay almost exclusively in my room. I did have to install a mesh aquarium cover because i was worried she would get into the tank while im at school or away. I very highly recommend a steel mesh cover for a tank. They are pretty cheap and all you have to do for tubing or cables is cut a few diamonds off with butcher scissors or pliers.
Hey man, Amazing video as always. I have one question. Is there any significant downside to using just one bottle? If I use the same recipe, but don't use the 2nd bottle with water, will it be harmful to fish or shrimp in the aquarium in any way?

"The bubble are working. But nothing comes out of my diffuser. There' are no leaks and bought the correct diffuser many have used on dyi co2 systems. Maybe my house is just too cold."
Try an air stone instead of diffuser, not enough pressure maybe. Turn off at night to increase pressure
I've tried all sorts of different recipes for co2 and yours is the best by a mile. Adding the galitine is a brilliant idea.
Great to hear!
Clear explanation! Highly recommend for first co2 beginners.
The ending 🤣🤣🤣 I cant 😂 cool video 👍🏻🙃so many tips

so of a night you don't remove the diffuser or anything just extra surface agitation via air stone or outflow ?
Can I use powdered gelatin or not?
Thanks for your video. It’s very clear and looks easy. What are the bottles you “pre-made” ? Water-gelatine-sugar? Or the whole mix including the yeast ?

@@MJAquascaping MJ, do i need to wait for the gelatin to become firm before i add the water with yeast?
@@Year-tk9ii awesome! Happy it works for you!
@@Year-tk9ii yep! First let it firm up. If it’s not firm you will get a lot of Co2 and the bottle will run out a lot faster.
Can you use saf-instant yeast in this diy method?
u can buy the cap for bottle for 1$ and 30 cent that made for making a diy co2 kit
Hi MJ, nice video.What diffuser do You use for low pressure system like this, most of the diffusers I have seen work only with high pressure system?
I prefer the diffusers with the brown ceramic disc, like the aquario, twinstar, dennerle etc.
But tbh every diffuser will work as long as your system is completely sealed
@@MJAquascaping Thanks for reply. I had one of the glass diffusers from amazon, one of the cheaper ones.The diffuser had a good review. I run DIY kit with citric acid and baking soda.Its with gauge always showing nice pressure between 1.5 and 2 but for that diffuser I had to open the generator full and it was almost not making any bubbles.It was air tight. I think maybe it was faulty or maybe only suitable for very high pressure. I connected cheap small stone now and it's making very tiny bubbles which is really amazing for this type of stone I think it's a lucky stone, one in 1000.All the best MJ, waiting for more of Your videos.
Can i use airstone as a diffuser?
Bedankt voor de duidelijk uitleg. Kun je voor de 'washing bottle' ook een klein flesje gebruiken 0,5L / 1,0L ?
ja! doe ik normaal ook, maar voor deze video had ik die even niet in huis.
Thanks for your information, it's great for low buget aquarium, I trying your idea ,and works great , Greatings from Prague!!!👍🙏
3 sheets of gelatin? Can I use powdered gelatin? how many grams would one sheet of gelatin be?
since it cant be turned off,, is it ok i put that co2 24/7 in the tank with plants only (no livestock),, will it kill the plants since the co2 still inject the whole tank day and night?
Perfectly fine to inject CO2 24/7 👍😊
Which CO2 diffuser do you recommend for you DIY system setup?
I was also wondering the same. Would love if someone commented. Or did you end up finding one?
@@amberwawa7185 I bought the twinstar co2 diffusor S
is there a way i can time it so that it is on at the same time as the light
Is it good to put this system out of the water at night?
I wonder if you could brew some cider and make CO2.
how does the gelatine work? is it just another food for the yeast to consume?
The gelatin makes it more difficult for the yeast to consume the sugar, or basically they will consume it at a lower speed, this makes the system last a little longer.
@@MJAquascaping oh ok, do you know any alternatives that would work? flour maybe?
@@dizzyguy7423 nah either gelatin or agar agar
@@MJAquascaping ok i’ll give it a try
@@MJAquascaping ph and sorry 1 more question 😅 is the gelatine/agar meant to be completely dissolved in the water?
Hi I've tried this system with my new diffuser and it needs alot of pressure to push bubbles through. How long does your system take to start diffusing bubbles into the tank? Thanks
Its answered at 11:50
Drilling the hole would be better, but whatever works is OK too
Nicely explained everything in detail. Thanks a lot
The English word for the black tool is Pliers
Great information, I'm going to try this. Thankyou.😊
The video is well done, nice and calm and then the end BLAM! Lol. Thanks for sharing this!
works great in a 20l aquarium. thank you. 🇸🇰
How? Mine just won't work. Can't even find any leaks. Do you heat your house all year and never open windows etc. Mine only worked the first few hours (probably due to warm water and that extra tbs of sugar) and stopped. Now a bubble every 10+ minutes if I'm lucky and still not a single co2 bubble out of my diffuser.
I’m about to end my dry start. They say it’s best to have a lot of CO2 in the water at first when flooding the tank. Can this be done by adding less gelatine and or more yeast? Or keeping the bottle in a warmer place? Thanx in advance.
Yep more yeast will for sure speed things up! if you wanna go really crazy you can also leave the gelatine out. But both these things will reduce the longevity of the bottles, so you will have to replace them more often. (2-3 weeks)
Can I use baking powder instead of yeast??
Thank you very much!
Will stone bricks made for oxygen work as a diffuser?
does anyone know how often you need to replace the second bottle with water for diffusion?
Great video, I'm no Aquascaper but am learning a lot about how to keep an an aquarium from your vids. I had wondered whether it would be possible for cat owners to keep an open-top tank, as I will be bringing home a kitten in two weeks... Can you offer any advice on how to manage your cat's behaviour around aquariums please? 🌿🐠🌱🐟😺🌿
We have 2 cats, and they just love to drink from the tanks.. 😂 they don't care about the fish at all. So we just let them drink from it, there's no harm in that.
@@MJAquascaping now there's a picture, thanks Mark, it certainly gives me hope that both kitten and fish will be able to live together in harmony. I saw a video of a cat diving into a full tank the other day 😅, this is my first time owning pets, wish me luck! 🙂
@@sweetdreamstime2266 I have a cat and a fish tank that stay almost exclusively in my room. I did have to install a mesh aquarium cover because i was worried she would get into the tank while im at school or away. I very highly recommend a steel mesh cover for a tank. They are pretty cheap and all you have to do for tubing or cables is cut a few diamonds off with butcher scissors or pliers.
@@wildfiretoff2789 thank you for the advice 👍🏽
Hey man,
Amazing video as always.
I have one question. Is there any significant downside to using just one bottle? If I use the same recipe, but don't use the 2nd bottle with water, will it be harmful to fish or shrimp in the aquarium in any way?
Not at all
@@MJAquascaping Thanks ^_^
Hi. Am getting 30-40 bubble counts per minute. Is it ok?
Would this have any effect in a larger tank? (50gallon)
You can scale this to any tank size. Just add more bottles or use bigger bottles with double the recipe! experiment with it!
How do you know the yeast isn't producing anymore CO2? Is it gonna stop bubbling? Or?
You will notice less CO2 coming out of the diffusor
Haha. Je kan beter een 5mm gaatje boren. Trek je je 6mm slangetje altijd waterdicht doorheen. Goede video verder!
The bloopers at the end though! 😅🤣
Have you got all the sugar out of your carpets?
took a while! haha
i have a air fed sponge filter, is that too much surface agitation for 24/7 CO2 to have any benefit from it?
Not too sure, just give it a try i think? 😊
@@MJAquascaping all right and what do i do with the liquid after its done bubbling.. distill it? 😏
Can i use a oxigen difuser instead of a co2 difuser?
Yep!
Hi, should i use jelly power instead of gelatine?
I used gelatin powder. One packet, -+5-9g is the same as three sheets. Actual jelly to make food is full of sugar, flavourings etc
