Mg very high, not dosing it though
Temp 77.4
Salinity 1.026 PH 7.9 KH 8.2 Ca 500 Mg 1800 No3 4 Po4 0.2 My magnesium stays constant around 1700 over time but I am not dosing anything but kalkwasser. I use Red Sea coral pro salt. I also dose NoPox and recently got my No3 and Po4 to 0 and held it there for about a week BUT my Mg was high before I ever started NoPox. What could make Mg stay high? Do I need to try to lower it? I do 30% water change every 7-10 days. Am I doing to much water change? Should I do 15% water change weekly or 30% biweekly? |

I would measure some freshly-mixed saltwater. Most often, high magnesium levels are caused by salt mix issues. That level is safe enough, so I wouldn't worry for now.
