magnesium uptake in sps tank

[Lampshade]

ARM's new mix is "high magnesium" but still not perfect. I dose extra on water changes with Randy's DIY recipie. Apperently Dolomite(Dolcimite?) in the calc reactor works, people have been using that for a long time.

Check salt mixes too, i use IO and it's low. Just bringing it up to 1300 at water changes keeps my tank balanced at about 1200-1250.
