Worst filter IMO. Good idea and principle with the water being forced through the filter, but as my cartridge got older the top of it seperated and made a little stream shooting straight up where filter seperated and caused about 20 gallons of water to flow all over the floor. I'll never forget my friend from florida was sleeping my living room on the floor and she came running into my wife and I bedroom at 2 in the morning telling me there was water all over the floor and the fish tank must have sprung a leak. Well thankfully it was just the filter but I threw it a way after that and will never use another one.zave2340 said:honestly chekc out the hydro filters....
