Does anybody know how to use the RJ-45 port on the back of the DP-4? Mine continually reverts to a previous setting in the software and has killed almost everything in my tank, I get it set right and then after everything seems fine i'll find the alkalinity is too high and its back to dosing 8x what I had it set at.
I intend to control this with an Arduino so I won't have to rely on the crappy controller that keeps killing my corals.
TIA
