Title: Lousy product
Review: Terrible filter. Impeller quit working twice. First time, company sent a new impeller, but it took two weeks so I had to buy another filter to keep my tank clean and the fish alive. Second impeller quit working periodically, once during a vacation. Also, the shut-off valve never worked and I had to put he canister into a bucket as it drained water from the tank during cleaning. I tossed the canister into the trash and bought a Penn Plax canister, which has worked flawlessly so far.
