Q: I’m thinking about using GFO in my reef tank, but this product is new to me, so I have a few questions before I go ahead and buy it: Does GFO really do a good job of lowering nitrate and phosphate? Can I just put this product in a media bag and place it in my tank? Also, I’ve heard that dust from the GFO can end up all over your tank if you’re not careful. Is that true? If so, how can I prevent that from happening? Thanks! -Submitted by Sarah Mercer
