I purchased this product along with the ROX.8 Carbon to use in the Dual BRS GFO and Carbon reactor. What an incredible solution to my phosphate problem! It has reduced the phosphates to below my test kits ability to measure. It's great. I don't have any problems with it causing any dust in the tank at all. It's great and I keep using it constantly in my sump.
