I just pulled it off the old tank because I'm putting a bigger one on the new tank. cleaned it up and added new ARM media, filled with RO water to keep the pH probe from drying out. Co2 bottle is full. pH probe has about 3 mos of use. Regulator is ugly, as all used ones tend to be but it turns smoothly and regulates precisely. Setup is 100% functional and 100% turnkey, just plug it into your APEX and return pump and make calcium/bicarbonate If you need it, I'll include my 1/4" return pump T adapter. there is nothing else to buy.
