So I have been using Rowaphos for years and before that was BRS high capacity GFO. All I can say is PO4x4 by Reef Interest is the best GFO I have ever used. Took a lot for me to say this because I have always loved rowaphos and didn't think I would ever use anything else. I can tell you phosphates are at zero. I would have to give the glass a light cleaning and right now I am on a week and half on the new GFO and haven't touched the glass or do I see anything on it. I wanted to let you guys know about this product if your not using it already. Oh by the way you can also regenerate the gfo with the regeneration salt they sell.
