Hi,
I'm keeping FOWLR, so maintaining my salinity at 1.018-1.019. However when i test the magnesium level, it's v low: 1050ppm. I tried to raise it using magnesium powder but still cannot bring it any higher than 1100ppm. Is it normal for low salinity to have low magesium level, if so how low is ideal? Any help is deeply appreciated. Thks in advance.
