I'm finishing a 40g breeder build and am checking out controllers. Here's what I need one to control/monitor:
pH, temp and salinity
Auto topoff
Return pump
Skimmer
Lights (optional as I may buy some with a built-in controller
Dosing pump(s) for kalk or maybe 2-part
Heater
I don't need every bell and whistle and am on a budget. I've looked at apex and reefkeeper but know some others are out there too.
Based on my needs, what would you recommend?

So I'm an old school ReefKeeper 2 user. Actually if I see them for sale, I'll buy it. No communications to cell phones or computers, but it controls everything on my tank.
