Good morning all, i recently got a smartwave controleer to operate 3 powerheads, one is a 425, a 240 and a 850. How do i hook up the 3 pwerhead cords to the 2 plugs on the smartwave. Do i just use a 2-1 plug? I know it can handle 100 watt, so hooking up 5 or 8 to one plug would be ok. It's for a 29 gal tank to get about 40+ water movement.
