Tissue Necrosis Ride it out or help out

[Colgan10]

My tank is in my office. Saturday everything was fine didn’t come to office yesterday and today my spongodies has some tissue recession. Alk is 9.2 calcium 460 not a ton necrosis but didn’t know I’d I needed to help it out. All other acros and montis look fine.

If just one, I would take measure of all critical stuff and then see if you need to slowly make any changes. Both that alk and calcium could stand to come down, but it could happen slowly over a few weeks.

I do not intervene unless I see something seriously out of whack or lots of corals start to get mad.
