woot finally got the canister filter to run without leaking! as it turns out, every single o-ring on it needed replaced...so i wrapped them all in plastic wrap, and that stopped the leak..
but i still have a problem with it. it has 1 intake tube, and 1 output tube at the bottom. the output tube splits at a t, and one end connects to a "diffuser" which flows out underneath of the water. the other end connects to another t, and on each end of the t is a bio-wheel filter.
the "diffuser" works...however the biowheel filter does nothing, the water stops approximately an inch before it gets to the second t.
