best co2 for nano tank 12L and 200L

[poeticwinter]

DIY VS Proper CO2 not sure which one is better and safe money too for running CO2 for nano tank 12L (25x25cm cube) and 200 L (3Ft tank)

this my tank been a while and the plant some been eaten dooh hehe... some cutting plants is hard to grow roots

There are several nano CO2 kits, but for your nano tank, I'd advise against having it, as the possibility of accidentally pumping too much CO2, in such a small volume will rapidly change the PH, and/or CO2 poisoning...causing deaths.

For larger tanks, there are endless possibilities. I've not done a DIY, but many have with success.. Just depends on what plants you're planning to grow, and having fishes that munch on them defeats the purpose of a CO2 unit.

yea i still thinking for upgrade with CO2, as my cube so small, might need bigger cube haha. did you using any CO2 on your shrimp tank? but mainly im looking for big tank as more plants on it. although i might thinking low tech with good lighting more best. i also still searching a good lighting for my 3ft tank as mine is just broken yesterday. either T5HO or Led, any one have suggestion for the lighting as well?

I'd definitely use LED….with the technology of them these days, PLUS not producing too much heat like the T5's etc… and your tank doesn't have demanding plants etc….LED's are the way to go IMO. Prior to benibachi, I used CO2 to lower the PH, but had a HUGE CO2 poisoning episode 3+ years ago, so I'm cautious with using them now :-(, plus my tanks only have mosses, so there's no need for it

As above if you have a nano then please use a led light. My nano used to have a normal light and noticed it did affect the temperature, now with a led I dont have that problem but note that the tank does heat up on hot days if the ambient is high.

In my 50 litre tank I have a basic fluval co2 unit. Just fill the little bell in the tank with the co2 and disperses throughout the day and generally empty just after midday.

question is what kind LED for my low tech tank 3ft. i've got offer for Ista led light/ Up aqua Z series. or any others good LED but good price also? T5HO is really conviced me though as 4x39W only $80

@warren63 i already do using LED for the nano tank, agree it does make heat if you using regular light and shrimp unhappy with the heat.

[daz88]

have you considered liquid co2 (e.g. excel) for your nano?

Led would be ideal for a nano, 1ft z series would do the trick. but you might need something decent led wise for a 200L especially if a deep tank, t5 an easier option there.

Also there are ways to control diy co2, like feeding it into a powerhead on a timer.

for nano i didnt using excel, as probably will harm the shrimp or make water parameter change.i consider to buy proper hood for the fish tank but it comes only with 3xT8 light. not sure if T8 good for growing low tech plant

T8's should be ok for low tech but you just have to remember to change the globes every 6mths. :victorious:

As already mentioned, be very careful with CO2 on the nano but for the 200L I use a Tunze setup(regulator & reactor) & it rocks! I don't use it on shrimp so I can't comment on that part. :encouragement:

I believe at the recommended dosing, Excel (liquid co2) is fine for shrimp including CRS, but if you have valuable and sensitive shrimp then prob play it safe. In which case why would you put in a 12L?

Further if you decked a nano with subawassang, anubias, java ferns, crypts etc in low light you could get away without adding any co2.

Thanks Daz88, yea im not really concern about adding additive to shrimp tank or CO2 :) might be for bigger tank but all still need wait till have $$ to upgrade any of my fish tank equipment :) Btw happy holiday, merry christmas and happy new year :)
