    Part of a nutritional breakfast for reef tanks.
  

*by P***C on Reviewed in the United States on 27 July 2020*

100 gallon reef tank. I go through a lot of seachem reef products. The larger size containers are cheaper to use. All my corals grow and stay colorful. My levels stay where I want them with regular dosing of this and a few other seachem products. I only check the levels once a month now.
