I have recently cured 80 lbs of fiji rock. Had it in a tote of saltwater with 2 circulation pumps and a heater for 3 months. Changed the water 3 times. It's now all good to go but when I tested the water recently phosphates were high. My question is: if I add some of this rock to my setup is it possible that the rock will leach phosphates in to my system? Or is there something I can do to remove the phosphates?
The rock was dead rock when I started it. Was in another setup for years prior...

You can leave the rock in the tub for another week or so. Throw a mechanical fitler on it, and dose SeaKlear, phosphate remover to it. This will remove phosphate in one big hurry. May take a week or so, so test after using it. Just a capful of this stuff will remove a huge amount of phosphates, but will leave behind its bonded form, thus the use of the filter.
