I have a PM2 and use the sg probe. Easy enough to set up and install, but not sure I would trust it for controlling the sg (it reports in PPT). I would use an ATO system controlled by apex. Maintaining the correct water elvel will controll the SG


180 gallon, 30 gallon sump, 3 250W MH + 4 ATI T5's, MTC MVX 36 Skimmer, Apex controller Reef Octopus CaRx

Current Tank Info: 2 Barred Rabbitfish, Red Head, Yellow/Purple, Hoevans, Possum, 2 Leopard Wrasses, Kole, Purple & Atlantic Blue Tangs, Matted Filefish, 2 Percula Clown, 4 PJ Cardinals, Swallowtail Angel
