Read up on varous threads and want to help as we must be neighbors here in Parkland. Consensus is as follows: 1. Loves Calcium and you will need something else to consume the calcium and compete with it. Add SPS, Clams, etc 2. Raise Magnesium as that appears to also help 3. Manually remove and place rocks upside down 4. Get Coraline to grow as fast as you can (similiar to #1) 5. Remove the rock, cook it, and start over. Good Luck...
