I was wondering how much space you should leave at the top of the tank, when filling it up?
My tank is 20" high (tall) and I fill the tank with water, leaving about 5" at the top. Is this too much?
I've seen other members tanks where only 1"-2" is left at the top.
Also, I have a canister filter and my water level is just below the filter outlet pipe, so the water sprays out through the little holes - should the water level be below or above the filter outlet pipe?
Thanks.
