Was wondering if anyone could give some advice. I've got a 110gallon SW
reef w/ a mud system, and a koraline c02 reactor. I've had the reactor for about 2months now and I cant seem to get my PH
up past 7.99, and at night its drops to 7.85. My temp is at 77-79 all the time and my Calcium level 500ppm, Alkalinity level 16dKH, Salt level .023, bubbles in the reactor are at 1/sec and the drip is at 50/min. I use a Salifert test kit for all my parameters except for the PH
I use a monitor(which is calibrated fine). I've also done several water changes to lower the ALK
and it works for alittle while but then it goes back up.
Any help would be appreciated.
