I had a Jebao CP-40 and it worked for a week.? Then the controller refused to hold a setting.? It would unlock itself and go to 90%.? I never caught it doing it, but after an hour I would notice a change in pitch (yes you could hear it) and it would be back at 90%.? The seller sent me a new controller.? It wouldn't run the pump at all.? Then the seller wanted to send me a new pump.? I sent the whole thing back.? 100%+ failure in 3 weeks was enough and the forums are full of complaints.So I bought a Maxspect.? 3 times the price.? It has a LOT more flow.? The controller programming is not easy to understand, but after messing with it over an hour it finally made sense.? The forward/reverse Gyre mode actually works (unlike the Jebao) since they give you a backwards set of impellers so it will actually pump in reverse.? You use one on each end so 1/2 the pump is working in either direction.? The controller can also handle two pumps.? All you have to do is buy a second pump at about 1/2 the price.? It will run them in tandem, or in opposition, or one pump delayed behind the other.? It can change between modes on a timer and I forget how many time slots are available for changes, but it is a bunch. There is also a connection for 12V battery backup.The controller had a problem (more on that later) and Coralvue was very quick on the replacement with very little hassle.? Their customer service is excellent.My tank is 7 feet long and the pump circulates the entire tank without having to run at full speed.?? You might consider trying one.
