I'm thinking of getting the digital aquatics Reefkeeper float switch kit. Do I need the dual float or the single float? Also, I'm wondering how do I set it up to my rkl? I have the pc4 that has 2 items plugged in already. The temp probe and the main head unit. There are no other ports to plug into. Should I get a phone jack splitter to make another spot to plug it into?
