Good morning Barb
In all honesty instead of investing in wave makers and or timers I highly suggest getting a tank controller. I use Neptune Systems Aqua Controller and LOVE it. This one unit controls my lights (Daylight, Actinic, Moonlights, Fuge light), my heater, Temperature probe, PH probe, Fuge pump, and 2 in-tank power heads. I had timers on everything before and honestly once I got the kind I liked that were dependable I had just about as MUCH invested in them as this controller costs. And I can hook my laptop up and see what the status of my tank is at any time from anywhere. I've only scratched the surface.
Good luck and happy reefing
