I've been battling the effects of the oh-so-effective biopellets in my 90G mostly SPS reef for some time now. Long story short, they kicked in hardcore after running in the tank for almost a year and stripped everything out of my water. That made things unhappy quickly, so I have been adding fish, and feeding the SPS/fish daily like crazy, and doing weekly 10G water changes with Red Sea regular formula. I also finally got my Ca/Alk and PH in check a month or so ago, near optimal conditions. In the last few weeks, most SPS have really turned around and regained color. My clam is also looking better too after a fresh water dip. However, two of my favorite pieces look like they are in trouble. My monster pink lemonade colony has not regained PE, and has had a "chalky" appearance for a few weeks. When I turkey baste it a bunch of dust flies off. Now today I noticed 2 branches in the center bleached. This could be the beginning of something bad 
I noticed my smaller colony of Strawberry Shortcake also has this chalky appearance, although it doesn't look as bad. I've looked very carefully for any pests but can't find any evidence. The SS and PL are a similar species of Acropora, so maybe there's just a condition or change in the tank they didn't like? I'm at a loss, as everything else is looking better than in a long time.
Anyone experience something like this?
