Re: Tiny super efficient CO2 reactor I have this filter in a shrimp tank. I just run the co2 line into where the air intake is supposed to be. It spreads a big cloud of co2. It is not as efficient as what you describe. I will have to try your method with it, though I may keep at least a small portion of the sponge where it is supposed to be so the shrimp don't get impelled. |
