Hey guys have a question about CO2 levels and PH in my planted tank. Here it is. How does oxygenating the tank with a bubbler aip pump affect plant growth/CO2/Algae??? I dont mean to ask an open ended nebulous question but heres my quandry.... I bubble the tank to keep O2 levels constant, and because I find it raises and fixes the PH in the tank. My problem is that I think aerating the tank leads to low CO2 somehow, because the plants are not quite as dark green as I think they should be, not really growing very fast, and I seem to be getting quite a bit of beard algae. I use iron and potassium supplements for the plants but they are all still very "middle" to light green with no dark green growth. Im gonna try a few days without the bubbler, monitoring PH. What do you think??
