I happened to check my tank last night with a flashlight (who doesn't?) and noticed for the first time an area at the base of a BC Grapejuice colony that had bleached with tissue recession. I'd been away for the weekend, but think I would have noticed it last time I looked, which was Thursday. Checking my parameters this morning I did have a low alk reading at 6.8, down from last Wednesday which was 7.9 dKH. I have not had any other changes to the tank physically or the water parameters.
There is a small critter moving on the exposed skeleton. As near as I can tell this appears to be some type of pod and not a flatworm of any type.
This rock cannot be removed to dip or try to superglue. Right now I plan to monitor and if it grows further I'm guessing my only option will be to frag healthy branches and epoxy over the damaged tissue, unless anyone else has a positive STN experience they can share to give me encouragement.
