Magnesium in my 6-month old 180 mixed reef is always low. Stays around 1180. I use Red Sea Coral Pro salt. Dosed with Seachem Fusion 1 and 2 which increased Calcium, but Magnesium didn't move much. Alk has always been around 10 to 10.5. Should I be doing something different? Here are my current parameters. Thx in advance.
