75 gallon mixed reef tank, 15 months old, can't seem to get chemistry stable on it.
Dosing RedSea two part for about 3 months, can't get good values on pH, Ca, Mg.
Ph:
- testing with calibrated Vivosun tester, 7.7
- testing with Hanna checker, 8.5-8.6
Calcium:
- API test kit
- fluctuating between 380 - 450, depending on... who knows what?
- dosing 12+10+7ml per day, today I changed to 12+12+12
Magnesium:
- RedSea kit, two kits measuring same values, both kits tested with a verified Mg sample, both kits measuring accurate
- measured 1050, started dosing slowly, 5+5ml, then upped to 5+5+5, now I am at 12+12+12
- at one point dosed 200ml, Mg raised to 1300, can't maintain it!!!
- I was afraid of dosing Mg too much, as I see concerns everywhere that once you have too much Mg, it won't go down
Alkalinity:
- my most stable parameter 9 - 9.5
- checking with API kit and Hanna checker
Please help with Mg/Ca/pH. My corals are growing, not as fast as I see in youtube videos, I am afraid Ca/Mg/pH are not ok. Can you help me?
