Anyone run miracle mud in an sps system??

I think Chingchai's reef tank uses miracle mud. It's as nice of an SPS tank as you can find.

I have used it four a year in my 240 and don't notice a thing. I also had to back off the water flow a fair bit in my fuge because it was stering it up so much it was going in to my tank.
