I had been using this with my UV sterilizer, but replumbed the tank using a manifold instead. I am the original owner, and have been running this pump at its lowest setting at all times. The body has a bunch of scuffs and scratches on it from cleaning off deposits and tube worms with the hard side of a tooth brush. Functionally the pump, power supply, and controller are perfect. The original box and unused inlet/outlet fittings are included. I’m asking for $400 with shipping included to the continental US. Let me know if you have any questions. Thanks!
