Maria James –
I’ve been using this mix for three months now and my magnesium levels have stayed stable. It’s easy to dose and works well with my Balling light system. My corals are thriving and water parameters are balanced.
Stewart Quinn –
Good product, reliable for maintaining magnesium. I noticed a slight difference in water clarity after a few weeks, which I attribute to better chemistry. Not a miracle fix, but consistent results.
Irene Sutherland –
The granules dissolve quickly and don’t clump. I use it every two weeks based on test results. My tank has had no magnesium spikes or drops since switching to this mix.
