    thanks for the reply, i actually just changed my sump design, my sump before was no biological or mechanical filtration, sumps that acro guys like to use.
    but a lot of dust sits on the bottom of the intake section where my octopus skimmer was, but then the dust slowly goes back through the tank settling on the substrate near the front.
    now i added a section to the sump with 6L of matrix and built up with sponges and filter wool, now the substrate is clean and at the moment no algae

    Hey Steelo! you are by far the best reef tank teacher on the net! maximum respect! I too am a noob and was wondering can I dose calcium and alaklinity using dosing pumps into the sump or does it have to be pre mixed with rodi water?

  • @mofoglenn333

  • @taknbyd4evr
    @taknbyd4evr 14 ปีที่แล้ว

    First of all thank you so much for your videos. You have made my life so much easier... Now for my question... I'm trying to figure out how the Cal and Alk co-inside with one another. Are you saying that it's almost like a see-saw effect? Where if the Cal is low then the Alk will be high and vise-versa? Right now I just did a WC. I'm at Cal 560 and Alk 13... I'm guessing as of right now to not start dosing just yet. I just bought this product today from the LFS. Thanks again Steelo!

  • @siloex
    @siloex 14 ปีที่แล้ว

    awesome video man... I purchased some of this stuff in the small bottles like a month ago. It didnt last though since my new dog found it and ate it all LOL... Well, he didnt really eat it, he just spilled it. but anywayj i didnt get to use it but im definately going to get more of this stuff and begin dosing just to get the hang of it. hopefully coralline algae will take foot with this this dosing. Right now though, i need to finish messing with the sump to create a stable environment first....

    i only have 2 chromis and morphs and finger corals so maybe i need to add more corals to use up the excess calcium, i,m running quad t5s, not sure if i need to go to metal halide lights.
    great video series, well done.

    @shardinio 13 ปีที่แล้ว

    @newyorksteelo thanks man! yeah ive read the dangers of overdosing and will be very aware of this! I will be doing it very slowly and testing constantly! am setting up an automated marine system and will be doing a video diary of the build and the journey. I hope you can find the time to check out my videos and give me tips along the way. thanks for your advice and keep your awesome videos coming ;)

  • @cheekboi18
    @cheekboi18 12 ปีที่แล้ว

    Hey steelo great videos. My problem w/ my tank is i have been adding seachem buffer in my system everyday for a week now cause my dkh keeps going down while my calcium stays the same. I also found out that now cyanobacteria have started growing. My tank is about 2 yrs now.

  • @Kephers7
    @Kephers7 14 ปีที่แล้ว

    @newyorksteelo
    Yeah I know. I mean my corals are find they arent hiding or anything. But heres the deal. Im dosing the tech cb a and b and trace elements. But other than things like phyto plankton, I'm not dosing anything. I have a 29 gallon with a 10 gallon sump/fuge with 8 pounds of live rock and cheato and i'm also using the fluval 305 for my crabon/chem pure/phos remover. I do 5-10 gallon water changes weekly/bi weekly religiously. Nitrates 0-4, phos .3-.5 little high workin on it

  • @iPhone4SEman

  • @taknbyd4evr
    @taknbyd4evr 14 ปีที่แล้ว

    How do you go about lowering your Calcium... I do weekly water changes and I am noticing that my calcium always wants to stay above 500 and I believe that is because of doing such frequent water changes...But what do you do to lower the calcium. I have salifert calcium and alkalinity test kits and the calcium never reads which means it's above 500 and my alk is around 9... Just didn't know if I should add alk to get my calcium to drop or what.... Thanks again for the help and awesome videos...

  • @Tydev13

  • @iPhone4SEman
    @iPhone4SEman 12 ปีที่แล้ว

    But like i said buddy i have the API test kit and it takes about 12 drops using the alk test kit so if i add more alk it won't raise my alk will it ps thanks for answering back so fast

  • @Zer00Monster
    @Zer00Monster 12 ปีที่แล้ว

    My ph is about 8.5 been running 2 months but I added 1" of live sand cuz I was about 3.5" sand bed at the time which was last week so the mini cycle which is happening right now on the dsb may have been the cause for the ph rise and yeah, until I get a alk and magnesium test kit I won't know for sure. I have yet to do a water change tho do that maybe the Easyier solution. It's a 55g system with hob

  • @paulwizal
    @paulwizal 12 ปีที่แล้ว

    First of all I would like to.give you props ive learned alot JUST.FROM WATCHING YOU VIDEOS,now my question to you is,i just bought two dosing pumps from BRS and the B ionic 2 part solution,now my levels are 400 cal. And 8.4 Alk Dkh. But I use Aquavitro salt which keeps my level somewhat in tact,but now I jus bought a bunch of SPS and with that being said using a salt like mine wpuld you still recomend to dose 10ml a day...or should I do so,but just test everyday after installing the dosing pumps

  • @saliva911
    @saliva911 12 ปีที่แล้ว +1

    my alk and magnesium are good so can i add the b ionic calcium part alone to raise the calcium or does it have to be both?

  • @shechshire
    @shechshire 11 ปีที่แล้ว +1

    It would depend how many corals you have & at what particular rate they deplete minerals but for a tank like your big one or how most people want it full of colorful corals yeah I agree. I don't like some two parts though... some add salinity which you'll cause you to make a freshwater change to bring it down.

  • @Hpu1997
    @Hpu1997 12 ปีที่แล้ว +1

    What's your opinion on calcium 2 part dosing versus adding kalkwasser to water ato?
    Some books prefer kalkwasser over 2 part and calcium reactor as the best. Kalkwasser seems the easiest to me. What's your opinion? Thanks

  • @sputnik790
    @sputnik790 14 ปีที่แล้ว

    @newyorksteelo Yeah, i dose 15ml of each component daily, considering 50 gal. main and 20 gal. fuge, minus LR/LS, about 60 gal. of a total water volume! Where do you keep your B-ionic, i mean you don't have to keep it in the fridge?

  • @lalnomair3414
    @lalnomair3414 11 ปีที่แล้ว +1

    If I do water changes every 2 weeks that means I don't really have to add supplements? If so how many gallons should i change on a 150 gallon ? Thanks

  • @miickyp
    @miickyp 12 ปีที่แล้ว +1

    Hi NYS. I am setting up a dosing pump to dose alk & calc & it'll be much easier to dose into the filter sock before the skimmer. Will this work or just reduce their efficiency? Thanks, Mick :))

  • @paulwizal
    @paulwizal 12 ปีที่แล้ว

    Using aquavitro salt in a 37 gallon with a aqueon model one sump,would you still dose 10ml of each everyday seeing this salt contains alot of each,or would you just dose 10ml and then test everyday,also I have over a dozen of sps and lps together...???

  • @calbileo
    @calbileo 13 ปีที่แล้ว

    hey steelo! instead of daily - weekly dosing's, can I just buy a Calcium / CO2 reactor? I have been told by many that if I just use a Calcium / CO2 reactor, I dont need supplemental dosing's.

  • @2112Danny
    @2112Danny 12 ปีที่แล้ว

    Would you recommend b-ionic calcium and alkalinity instead of kalkwasser?

  • @miickyp
    @miickyp 12 ปีที่แล้ว

    Ah thankyou, I've just tried it and it disappears in seconds. This is my final question, sorry for being such a pain. Do you recommend using the 'night mode' on the power heads, or do you leave them in full 24hrs a day? Thanks again for all your help :)))

  • @ryjack26
    @ryjack26 14 ปีที่แล้ว

    cool beans, i am really liking this kalkawasser, ive been growing some good coraline algea, which is what im looking for b/c i dont have anything like sps's. Is b-ionic expensive? how long would thoes containers last for ur 90g system?

  • @sputnik790
    @sputnik790 14 ปีที่แล้ว

  • @VeryBadReputation

    Hey Steelo, do you add the dosage all at once?
    Doesn't that make your pH go sky high?

  • @vdre3
    @vdre3 14 ปีที่แล้ว

    @newyorksteelo yes thats what happens it becomes somewhat of a flaky effect after the alkaline is added...well as of right now i dont have any test kits to test my tank what i do is when i go buy my water at my lfs i ask them to test my water nitrate, nitrite, have been good at zero but my ph has been low between 7.6 to 7.8 i have to add marine buffer to get it right thats another thing im not sure why it gets low but i dont rember what the other specs are...am i putting my fish at any danger?

  • @NerdistAquarist
    @NerdistAquarist 14 ปีที่แล้ว

    I purchased the B-Ionic additives today after watching your video. I used to dose several trace elements individually, but since B-Ionic already contains all the trace elements it will cut down my dosing. I don't know if one day of use makes any difference, but the polyps on my pagoda coral has been shrunken since I got it from my LFS. After the first dose, they actually looked more open and full. Keeping my fingers crossed...

  • @Birdwrasse4

    Hi newyorksteelo.....
    Great videos....really informative. I'm getting ready to start a FOWLR but at some point i'll be adding some soft corals. so when i initially start my setup should i be dosing with part 1 and part 2? I'm just wondering at what point should you start dosing your system....thanks

  • @jrlocascio

    @newyorksteelo When you recommended to @klok95330 to do water changes in "series" until he get the right parameters is a weekly water changes or every 2 or 3 days ? I'm thinking on doing that to tray to even the Alk and Cal as you recommended in you comment and then add both when they drop.

    Ok, after a few days and Ive gotten my dkh down to about 13 and calcium is at 380-400. So Im getting that in order. I also just took your advice and got a phos reactor as well. My next purchase is going to be a RO/DI unit. Any recommendations for one? It has to be on that attaches to the faucet cause I live in an apartment.

    Whenever i used my test it here are my results..
    Alk - 15 drops.
    Calc 25-26 drops.
    Those is are the drops i do until i get the end results... It means that i have high alk and Calc right?... How do i fix this.. ive done water changes and still same results..
