Is there a DIY way to add mag to your system? Like a homemade recipe or such? My corals are not growing and the only thing I don't test for/ dose is magnesium. I've heard low levels could be stunting my coral growth.
I used the 2 part from BulkReefSupply with great success. Brought my Mag up to 1400 and kept it there. By doing so, it really helped my corals growth and helped with keeping Calcium at a higher level than I was able to before I started dosing.
