For phosphates get a reactor and add GFO to it. Granular Ferrous Oxide works the best.

What kind of reactor?

You can get a reactor from Bulk Reef Supply or Marine Depot. I would call BRS and tell them your tank size and let them suggest the best option. The reactors are under 100.00 and then you need a feed pump that shouldn't cost more that 40.00. You just want to run enough flow through reactor to just tumble the GFO.
