Marie, I thought about that, but really can't see any fish nipping, and I've watched for hours straight. And I had strong PE with these fish, it just stopped after switching salts.

Maybe the substrate in your water column is sand-blasting them =)

Ya, that's my original thought, irritation from the turbidity. I swear I'm losing 30% of my light to the dust cloud!

Darren, pretty sure it's not fish, I have mostly large tangs and a couple of large wrasses, 4 clowns. No known coral nippers.
