Good call. Slow and steady wins the race with phosphates. Oh, and if your corals start looking pale, back off the GFO a bit. They'll tell you if they're hungry.

Exactly this. Also, keep an eye on alkalinity. GFO can sometimes cause it to bounce around if you're not careful.

Forgot to mention, chaeto in a refugium works wonders too. I run mine opposite the display light schedule and it's like a phosphate sponge. Plus, free pods for the tank.
