I struggled with phosphates for many years. Brown algae everywhere. The GFO helped control it but it was just a band aid and not a cure. I must have spent more money on GFO than anything else in the tank. I read an article on Vodka dosing and decided, why not. It took just two months and it was like magic. Phosphates and nitrate at zero. I barely clean my rear glass anymore. I reduced the dosage and now I just add 3 cc daily. It's been ten months now and tank is better than ever.
