I ran across a seller "reef chili" or "bulk reef supply" that is selling GFO on the cheap. Now when I think about it if a manufacturer keeps the extras out any GFO should be just fine. However,..... that is why I buy name brand GFO. Carbon is touchy I buy phosphate free name brand carbon for my fresh water tanks because cheep carbon contains phosphate.
So.........What are your thoughts on cheap GFO in the reef?
