I'm trying to construct a wave box for my home aquarium but I am having trouble finding a timer that can switch fast enough to operate it properly. Does anyone know of a timer (preferably cheap) that can switch every few seconds. The faster the better as I need the pump to just turn on and off every 1-5 seconds depending on the hight of the desired wave, and the timer needs to be adjustable.
