Any updates on this? I've had a few chalices and blastos starting to melt away as well. The skeleton looks pink under the tearing tissue in areas and white in others. I've seen it start at the edge on some chalices and in the middle of the polyp mouths on others. It just starts falling apart from there. I've been testing my water parameters with multiple test kits every other day for over a month. My alk is steady at 10.6 dkh, salinity 1.026, Amonia 0, nitrate 5ppm, nitrite 0, PH 7.95-8.15, calcium 420ppm, Mag 1520ppm, Phosphate .4ppm. I've been running gfo and started dosing vodka to get my PO4 down but it won't get any lower yet. This system has been running for 7 years now. A friend thinks I may be having rock leaching PO4. I don't know if PO4 is the problem or if it's bacterial. Been fighting this since December. I've lost a few very expensive colonies. I'm thinking of trying the Intercerptor. Any thoughts?

Thanks...
