You could do a few big big water changes. When i cooked all my rock for my 125 I waited for it all to cycle and then the p04 was really high I did a 100% WC on the rock and washed it off quick in the old water put it in new water added a bag go GFO close to the Power head and next week tested again and P04 was gone
For the most part the phosphate is in the water not the rocks
