Review on Kent Marine Magnesium 16 Ounce Bottle by Christie Stephens

works like magic when it comes to ridding your aquarium of moss. I took my mag from 1400 to 2100 in a week and after another week all my mosses were gone. I kept the store raised for another 2 months. Make sure you do this or your bryopsis will come back. Also remember to remove the charcoal and any other chemical filters you may have. GFO or Phosguard are fine.
