I have a apex system for sale. It is the older orange and black apex with display, PH probe, Temp probe, and the four outlet power brick. This unit can measure temp, ph, ore/ph, and has v1/v2, v3/v4 capabilities. I am asking $200 shipped. Nothing is wrong with the unit. Broke the tank down and no longer need it. Thank you
