I use a RK2 on our display which controls the fans , and heater as well which can be a bit difficult with a nanoreef ,and the frag tank I just use 2 heavy duty timers for pools/ponds and spas the 2 heavy duty ones suck since you can NOT change out the battery backup with out loosing your programing

I have also heard nightmares of the coralife strips as well so I shyed away from those , however lowes and I am sure other home improvement stores carry strips with the timers in for 1/2 the price of the coralife strips
