Works.
Works like it should. Gave it 3 stars because the price is absurd for what the product is. Google how to diy this product and you’ll never spend this much again.

I use all the Red Sea products! My corals all look super healthy and are growing, and all my parameters are darn near perfect! Go to the Red Sea site, put in your tanks information and get there list of how much to dose.
