Hi, this may be a silly question, but I am getting different answers from friends to petstores.
I have a 77 gallon tank, just bought a rena canister filter. Do I have to have like a bubble curtain or some sort of bubbles going into the tank? Was told I have to because not enough oxygen for the fish if I don't. Is this true? If i had a filter system like aqua clear 70 that splashes the water, instead of a rena filter that the hoses are under water then I would not have to worry.
Thanks, Paul
