Review on Red Sea Foundation Magnesium Supplement C Fish & Aquatic Pets by Krista Johnson

I love it! Very easy to dose. I have a 180g reef with a 75g sump. For some reason I've always struggled to keep the balance between kh and calcium. To have calcium at 420 my kh has to be around 7 for the most part, which isn't great. But with this product I can easily keep my kh at 10 and my calcium at 440! In addition, it maintains a stable pH. I will definitely be buying them from now on and would recommend this product to anyone with a passion for the hobby. hp For the first dose, the pH stays around 8, but rises to 8.2 after about a day.
