Reef Central Online Community - View Single Post - Need a little help dialing in my Geo 612

I have a Geo 612 with a Reef Fanatic CO2 Regulator/Solenoid, Pinpoint PH controller and Aqualifter pump.

I have the controller set to come on at a PH of 6.8 and shut off at a PH of 6.6. My calcium is right at 425 and has been for a few days, but my Alk seems to be creeping up a bit. It is now at 10.1 DKH and has been increasing by about 0.3 per day. I have my effluent rate down to a dribble. The bubble counter is around 90 bpm.

How can I control the Alk so it does not increase any more?

Thanks
Ray
