I have the X10 Dimmers hooked up to my MaxiJet powerheads, it takes them to 50% flow at night and brings it back up during the photocycle. I would assume that regular dimmers would have the same effect. Note of caution though, dimmers get hot when they are dimming something because the energy not used is channeled through the dimmer to the neutral line. Make SURE it is overrated for your pumps, ie if the pump runs at 100W, use a 200W (thats just me).
