I have a new 55g planted tank that I started about a month ago. I am doing pressurized CO2, dosing EI, etc. My question concerns aeration. I have removed both sponge filters to help keep the CO2 in the tank to be used by the plants. I have a powerhead in each corner of the tank to create a ripple on the surface of the water and to circulate the CO2. Will this along with the plants produce enough oxygen for my lightly stocked tank (8 corydoras pygmaeus and 10 Boraras Maculatus).
