I dont normally recommend using chemicals but if your PO4 is that high I would probably get some Phos down (sorry this is probably the wrong name, I know its a liquid product from Seacare) to dose to the tank to reduces your PO4 as its so high.

Then use a good quality GFO.
Fauna Marin and Rowa would be the two best product then TLF IMO
