Has anyone heard of this stuff. It's kinda pricey but it does claim that 8 oz. removes at least 1.5 ppm of phosphate in 250 gallons of water. That's a ton of phosphate. Does anyone know how it does that, and has anyone used it personally. I wonder if this means that phosphate reactors will be a thing of the past.
