I have a 405 canister filter, 30 gallon aqueon HOB , AND if I can get the piece of Crap api canister (50gallon) to stop leaking filters on a 50 gallon tank. Too much? It's not alone in the tank tho. I have a eel in the tank that went after the tig, freaked me out, but I think he thought the streamer was a worm or something. Keeping a close eye on that eel.
