Not sure if this is what you are asking but I let the Marco rock soak for a week in RO water. I tested the water for Phos and there was very little increase so it was hardly leaching phosphates. For good measure, I changed the water and let them soak for a few more days testing for phosphates again and seeing no increase. Rinsed the rocks off and put them in the tank!
