Brad, thats stuff looks like crap. Must be driving you crazy.
Funny how we do all the things correct, spend all that money on huge skimmers, ro water changes, etc, etc,etc and something still gets us.
Enough to drive an aquarist to keeping goldfish.
I have no idea, short of constant cleaning, how one could get rid of that algae. I have never seen it that bad in a top quality tank like yours.
I wonder if one of the treatments helps it along, like red bug treatment or something else. Seems like a hord of good aquarists are experiencing large bleaching events or other sps losses, when doing something major like a tank or light change. Despite being careful, {I was and so are most of them}.
Perhaps ozone may help, it does clean the water. If you do, be very careful you dont bleach your sps from the clearer water.
I have read about the peroxide use, but IMO, you gotta have %#$@ to dump it in your sps tank.
