I am looking into setting up an ATO on my system, but I am a little confused at how these things work. I have a reefkeeper and was wondering if all I need to do is set up a digital aquatics float switch in my sump and run a line from my reservoir (5g bucket) to the sump with some type of pump for the bucket? If I am understanding this correctly this is all I need? Does anybody know if a tom aquatics aqua-lifter dosing pump will be OK for this set up? The pump needs to be connected to my reefkeeper so that it can tell it to shut off when the float is closed, correct?
