I think I'm getting the apex lite this weekend. Just because I can't afford the full system. But I can add energy bar and additional modules and probes down the road. It can do anything you can think of. Main reason I would get it for fail safes. Can use float switches to turn pumps off if water level is too high and can add water sensors as well. Not to mention control lights, heater , skimmer, return pump and auto top off. The options are endless.
BUY IT! Do you plan on getting apex full system with energy 8 and ph and temp probe??
