For the past week I have been batteling low calcium 330-350ppm and no matter how often I dose/overdose(reef advantage calcium) it wont get above that level. dkh is 11 to 12, ph is 8.2. The first thought would be a bad test kit-but I had CPE check again and they get the same on all 3 tests. I dont really have many corals that require higher CA levels but I have never been this low. I tested the Reef Crystals salt and it is fine?? Any advice on this would be great! I also added some Kents Tech M hoping that would help but it has not. I did do a 15% water change Sunday but still got low CA readings---Salifert and Seachem test kits BTW
TIA
