Have any of you ever heard of the Natural Wave Multi-Cycle Pump Timer by Aquarium Systems? It is a power strip with 5 plugs that allows you to adjust the timing on 3 of the plugs to (I believe it was) 30 seconds to 3 minutes. I know that most wave makers are not very good for powerheads because they aren't made to turn on and off all the time. It says that they recommend using the Maxi-Jet PH Powerheads.
