Is the pump pulsing? What are the deminsions of your tank? What wave box did you get. Did it come with a controller? If you bought one of the wave box extensions, it requires a controller. Do you have the top of the box out of the water? It takes a bit of time to dial the wave boxes in. There was a bucket of water and eletrical outlets set up so you could test pumps. I tested three other wave boxes for people and two of them worked great. The third did not say it had been reconditioned and the pump did not work. I had waves going pretty quickly on the working ones, but I have used them before.
