I'm planning on buying a 125 gallon tank. I want some live plants and some community fish with 4-6 Angelfish eventually when conditions permit. I am familiar with the Emperor 400 line as I had them on a 75 gallon tank. Noise level does not bother me as the house is always noisy anyways, plus I never thought they were loud unless the water was too low. Will two emperor 400s be enough filtration for a 125 gallon tank in the beginning? I will eventually buy some kind of better canister filter.
