Review on Hydrofarm Active Aqua Pump Outlets by Amanda Spencer

This is a long term review. I bought the pump in December 2012 and kept it running until July 2017. It still worked, but very noisy and very little air. This is very good for these pumps. All rubber membranes harden over time. This one has lasted as long as anything I've bought. My biggest complaint is that I don't see any replaceable diaphragms for it. Since they always go bad, there must be a substitute. I'm sure some other brands of diaphragms will probably work, but over the years I've bought many that don't work. Note that the pump was never still, but it wasn't bad until she got older.
