mistermoose that is exactly why i mentioned pondmaster i have used many pondmaster pumps, in fact this is the first one i've purchased in 3 or so yrs and it pumped through a canister system a lot of back pressure. i should have been suspecious when the pump redesign looked like a generic china pump. Pet Club replaced it, but, i'm not sure how many times they will do that, it was $159 plus tax.

pet club didn't have to exchange it, but they did so i am grateful for that.
