I've had my tank up and running for about a year and a half and have been adding coral for about 6-8 months now. My tank is using about 15ml of Alk a day to maintain 8.6 but my Ca and Mg stay consistently high with Ca over 480 and Mg over 1480. I have a Red Sea Reefer 525 which is about 140G total volume and I change about 20% water weekly and use HW Reefer salt. I expected my fairly large WC to help keep up with dosing needs but I have yet to dose any Ca since I set my tank up.
Are my WC's just doing that good at keeping up or what could be the cause of no Ca consumption in my tank?
