Do most planted tanks run normal pump ariation or not? I assumed yes until recently it seems like maybe most tanks don't? I guess the plants provide the necessary O2 for fish?
Just curious. I thought I knew the answer but now I'm doubting myself.
Also, I'm going relatively low light, hopefully no CO2 to start, and light fertilization- will ariation add CO2 to the tank, esp enough for the plants to at least grow slowly? I.E. assuming no CO2, it is better to run the pump than not, right?
