Well, I have been dosing calcium via liquid additive into my 155 gal tank because my salifert test kit was reading 350ppm. I added enough over two days to raise it to 425ppm according to the directions. I retested the calcium after two days... still 350. I buy a new test kit (salifert) and retest...now 650. I check calcium with two other test kits - red sea and API , both 650ppm. I guess my calcium wasnt 350 to begin with. Stupid, faulty test kit!
So basically I have way too much calcium in the tank right now. My ALK/dKh is 10.4. I'm trying to dose just alk right now to maintain it and not dose calcium. I also did a 10% water change. I assume the [Ca++ ] will fall on its own as I maintain Alk.
I guess my question is..... is 650ppm dangerous or detrimental to coral growth in any way? I know it can clog venturis and pumps but I'm more worried about my corals. Mostly zoos, leathers, few acros/montis (small to med size).
Advice, thoughts or concerns?
