IMO, i would test the rocks for phosphates first by sitting them in just enough saltwater to cover them that you've tested for phosphates and known good for at least 1 night.then i'd test the water again. If the water shows phosphates then the rocks are contaminated and are leaching phosphates...

if you can, take one of the rocks and soak it into a bucket of new saltwater overnight, then test the water for phosphate. if you get a reading, then the rocks are leaching phosphate.
goodluck!
