I'm guessing that you're not running your gfo in a reactor, I highly recommend using one if that's the case. You can order a all the parts to make one for about 30-40$ on Amazon including pump. You can also get the high capacity gfo from bulk reef supply and it will really pull the phosphate out better than some of the cheaper gfo.
