DIY CO2 System

[azn_fishy55]

Does anyone have a DIY CO2 system that is not too big or not too small for a ten gallon tank?

See CO2 sticky in this forum for good links -- standard 2L works but 20oz bottle (closer to Hagen Nutrafin) does too. Could use a powerhead based diffuser with short tube, or small bell type, or maybe use your filter.

could also pump the DIY CO2 right into your HOB filter intake, but use an airline reducer so you get smaller bubbles that'll break up easier in the filter impeller.

AquaClear filters can handle this...any other decent brand should too, but I wouldn't try it with a Whisper.

powerhead based diffuser?Airline reducer?

powerhead diffuser: powerhead and gravel vac...search aroudn and you'll find plans and pics
airline reducer: converts from standard airline diameter to micro line (a.k.a. Eheim sized airline)

I have the plan for the CO2 system and I want to use a powerhead diffuser. How would I do this?

powerhead diffuser? if your talking about putting the co2 into the vinturi intake that would not be a efficent design.. there is a design for a powerhead powered reactor with the DIY CO2 link that I give out?

How would I connect airline tubing to a small powerhead?
