Phosphate Minus?

[JACK50REEF]

Anyone use this product? My friend gave it to me saying its very similar to rowaphos. It looks similar to rowa phos. Has anyone used it with valid results?

It would be a brand of GFO (like Rowaphos). There are lots and lots of reselling brands available, but not many primary manufacturers, so many of them would be the same as others. That said, I do not know exactly where these folks get their GFO.
