It's my understanding that ~0.03ppm PO4 is optimal for sps tanks. Any particular reason you want it lower? I would expect corals to bleach out if you pull it down any lower. If you still want it lower though, GFO would be the only way I know. The more you use, the lower it will go, but if it's already that low, not likely you'll need much.
