What are your nitrates at? Sometimes if your nitrates are low you will get a high reading on phosphates.

My phosphates were way up there when I first started my tank 3 years ago. I couldn't even control the phosphates with GFO and Fozdown. But my nitrates were undetectable even with the Red Sea Pro nitrate test kit. I started adding nitrates and my phosphates dropped right down and my corals coloured up.

Apparently nitrates were the limiting factor and once my tank had nitrates the inhabitants in the tank were able to use the phosphates and the phosphates dropped quickly to near 0.

If you have moderate to high nitrates dis-regard everything I said.
