my wife bought me a reef keeper elite for Christmas. Took a little while to figure out the programming but I really like it. Right now I have it controlling my lights, heater, moonlights, and tracking ph. I'm getting a salinity probe soon. I'm sure I will have it doing other things before it's over. So far so good.
I haven't figured out how to set up my float switch for my ATO yet but it will soon be controlling that as well. I would like to get the dosing pumps for it at some point so I can get rid of the one I have.
the float switch works well. I put mine next to the return in the sump. and plugged an aqua lifter pump up. Its a slow drip and works. just keep the airline tube above the water in sump to prevent back siphoning.
