So I have a question. People say you don't need air stones (regular air injection) in your tank because the surface area of the tank and good quality water circulation via pumps, etc., exchange more oxygen than an air stone could.
Well I don't use air stones and have never had a problem with fish. I only use air in one tank, which is a small hospital tank and it's usually empty with just nice calm water and air.
So then plants. People swear by co2 diffusers to help plants grow. Well if oxygen stones don't help fish, why do co2 stones help plants?
I don't blow co2 over my house plants and they do just fine... granted they get a lot more nutrients from the soil than I think aquatic plants might be getting from sand (I don't use substrate for plants) but still, why the co2?
