okay, so a few months ago i bought an aquatop cf-500uv filter. i had it set up for about a month when i realized some of the fish had the ick. so i put the fish in a hospital tank. they're doing a lot better, but im just about ready to get everything set back up. i hooked everything up properly, tank is full, canister and tubes are primed. i turn the dam thing on and it runs great. then just about when the pump has forced out just the last little bit of air bubbles, one of the locking tabs (the ones that give all the seal pressure, first ones you have to lock) starts leaking..progressively worse the longer its on. ive done just about everything i can think of, a part from taking it completely apart. if anyone has suggestions or had the same experience, please help. the only possible thing i can think of is maybe the o ring...but its soo new and i cant find anywhere online that sells those.
