OK. So after further review I think I am going to buy the
ReefKeeper Lite + SLX Expansion Unit w/ FREE pH Probe http://www.marinedepot.com/MarineDe...ums-Digital_Aquatics-DA11311-FITEMOMI-vi.html I don't need the PH probe, but I'll need the expansion unit. I'm also going to buy the
Float switch kit http://www.marinedepot.com/Digital_...ries-Digital_Aquatics-DA1413-FIDPETAC-vi.html to attach to the expansion unit. I am not crazy about the single float switch, and I like the electronic eye and float back-up of the Tunzi ATO, but I can't see buying both the Reefkeeper and the Tunzi. This would get me my ATO, Heater controller, and in the future, maybe hook my Reefbreeders Photon LED to it as well. I'm going to buy the float switch first, actually, just to make sure it will mount properly on my tank.
I think this is sound, no? Thank you for all your help everyone. I am pretty exited about this.
