GEO 618 setup


New member
I recently got back into the reefing game and acquired a turn key tank utilizing a Geo 618 Calcium reactor. I've had to refill the CO2 tank recently and now the Apex is turning the CA reactor on much more frequently, enough so that the tank PH went from 8.02/night and 8.27/day to 7.93/night and 8.05/day. No settings were changed, I simply removed the old tank and had it filled. Any suggestions on what steps should be taken to get it dialed back in?
