Magnesium?

Almost all my corals are the same size as when I got them. My other numbers all seems normal.

Salt 1.025
Calcium 420
KH 8.6
Mag 960(have been raising with tech-m now at about 1200)
Temp 79.2
Using a D120 LED light

Any thoughts on this?

Thanks.

IMO you're wasting your money with tech m unless you're trying to get rid of bryopsis, dont get me wrong, its a good product but there are cheaper alternatives that work just as well (just dont get rid of bryopsis). Bulk checmicals are the way to go, you're not paying for water that way, 2.99 (or somewhere around that) gets you a lb of bulk magnesium chloride, calcium chloride or soda ash.
