There is a whole thread dedicated to this: http://www.reefcentral.com/forums/sh....php?t=2453931

I have really good personal experience with MarinePure. Just ensure that they are in an area where a lot of the water flows through it. And that it is submerged. When swapping over from already established live rock, you'd want to use established MarinePure as well. Otherwise it may take a while to see decreases in parameters due to the time needed to propagate enough microbes in the block.

Used correctly, it can definitely lower nitrates as well, to almost non-existent levels.
