I'm thinking it's the controller because both waveboxes are controlled off the same unit. The controller powers on and you can see the little LED's switching on and off but the pumps themselves, both of them, remain off. I tried bumping the impellers in case they were just having trouble starting but that didn't do anything. To actually remove the waveboxes and take them apart will be a bit of an effort because of the tight spot they are mounted in .. but at least taking them off the controller to see if that is the problem should be an easy enough first step. If they power on and stay on without the controller in the equation then at least we know it's the controller and not the stream pumps themselves. And yeah all my Tunzes are the old style streams so I guess at this point if anything further on them goes then I just start saving the pennies for a Vortech.

Would a single MP40 be enough in a 6' tank? I think a MP60 would probably be too much? I was really hoping to get swish-swish wave effect with the polyps in this tank if/when I ever get to the point I'm comfortable trying corals in it...
