D-D RP-100 ROWAphos GFO Phosphate

I've used this stuff for years with exceptional results. I've only found that Marine Depot carries it. I'd like to hear if anyone else has used it or their experience. In my opinion works better than GFO and is cheaper. I haven't had a outbreak of cynao since using this product.
