Review on TL Reefs Bayoxide E33: The Ultimate Granular Ferric Oxide Phosphate Remover for Saltwater Aquariums by Sandy Martin

Product works as described but very dusty. I've used granular GFO before and know what to expect, but most of my jar is much finer than granulated, more like a powder in most tablespoons. I had to drastically reduce the flow through the reactor to prevent the GFO from being pushed out of the reactor itself. Even using the extra foam didn't prevent the product from getting into my pan. Again, only the flow was reduced A LOT to prevent this. It actually does the job I wanted. I just wish it wasn't so dusty and contained more granules. I would consider buying again as I personally prefer pellets over industrial grade.
