My FX5 is 3 years old and no problems yet (touch Wood) I have changed a couple of pads and clean the spounges 2-3 times a year each max. water flow is as good as ever. It runs a 6X2X2 planted community tank. I gotit on special for $375 but I see them for $495 at Petbarn. Its the only cannister I have owned so I cant compare it to anything.
