i change my GFO every two weeks ^
really you should test so that you know when to change the gfo , or you are just throwing your money away I mean gfo should last when p04 is under control a month and a half or so maybe longer when you see the p04 starting to go up that is when you change it, also you could be stripping vital nutrients from corals that need p04 and n03 to survive
