Brought up my Mg levels to normal
Brought up my Mg levels to normal after using a few other products that didn't work. I merely put about 4oz of this in my RO tank once a week. Tank size is 180gl reef.

great magnesium
This is a bit more work than the liquid stuff for sale but the results are fantastic in making coraline grow and stabilizing magnesium in a reef for the corals. Seachem really has the additive market down pat for the most part. I've been using this product for years with great results and no suprises.

Great Price!
We buy in bulk and the price is right with this. It does it job and keeps our 75gl reef healthy and beautiful.
