I Love It!

So I bought this at a local fish shop. I was looking for Kalk and they were out. The sales rep talked me into this and I figured I would try it. I have now been using this with my AutoTopOff for three months and have not had to spend what I normally spend on other chemicals such as mag, ca and other trace elements. This has cut my expenses of maintaining my 300 gallon reef tank in to a 1/3 of what they used to be. I just one 16oz jar a month in what used to be my Kalk reactor. I still have to add CA because I am a heavy SPS tank but not nearly as much. Everyone that sees my tank says I do not have enough light, and or flow but the growth I have is matched to none in my area. My corals are growing at a rate most people dream of. I can only give credit to this product to keep my levels stable so the stress is almost gone. No Stress equal great growth! I love this and I will never go back to Kalk!
