Power outage for three days. Had battery powered air stones running, but still had losses. Scooped out dead fish, did a 25 percent water change. Most of the corals seem to be coming back fine, except these two toadstools. One toadstool (white) the top is complete mush but the stalk is firm. The other toadstool (long polyp) has a giant hole in the crown, but the stalk is also firm. Cut tops and see if survive or pull the whole coral out?
