I'm looking for suggestions on setting up some automation on my two tanks. Normally they are fine, but sometimes they get too hot (82), which is when we turn on the fans, but if the temp drops (78) and we forget to turn them off the water temp drops (74) even with both heaters working. I'm looking at a suggestion on which system I should get to help turn the fans off/on based on the water temp, and maybe turn off the heaters as well in case one goes crazy (had that happen once). We don't get big swings, but enough that I'm convinced it is time to make the investment. I have to buy two setups (display + frag tank), so cost is a bit of a factor. I'm thinking of the Reefkeeper Lite + SL1 vs. Neptune Systems AquaController Apex Jr w/ Display & Temperature Probe. Any suggestions? I've never paid attention to this, so starting from ground zero.
