Re: leaving CO2 during the night.. controlling algae I'm not sure what Erio's experiment is intended to test. Whether the biology textbooks are right? Maybe they aren't or don't apply but I think a more interesting test would be to provide CO2 during the dark time and then see what the effects are on aquarium plant pearling and algal growth when it is shut off for a longer and longer time during the light period on an established plant tank with some algae problems. |
