Now the tank is about 1.5 years in and I'm still leaching PO4. Other than pulling the rock out and replacing, are there any other options?
Really don't want to replace rock but don't want to be fighting this in another couple years as well...

If the tank is already 1.5 years old. The rock would have had ample time to purge itself of any bound nutrients. Phosohates can only bed themselves so deep into the rock. After 1.5 years of potential purging opportunity there would have been more then enough time for it to have been purged out. Take this how you want, but your nutrient issues go deeper then your rocks. Granted after 1.5 years the rocks can be a contributing issue now again as they may very well be full again.
