I would frag it into 3 pieces...the dead one, and two live ones just to try and ensure that at least one survives.
I just did a vacuum session and water change. Looks like fish pieces floating in the tank...not sure what that is all about, but the fish aren't trying to eat it, so maybe it is something else.
One table is sliming up crazy like, but I think that is a response to the air "injection" when I vacuum the system down until the sump runs dry.
I moved the chalice to front and center, right where the old tort was. Since I have the Vortechs turned down and the middle lamp is in the dish reflector, I think this will be a good spot, if not temporary.
Tank looked very good this morning so my progress continues with the brown algal/bacteria bloom. I really need to blast the rocks too. I think I will start cleaning the glass as well, maybe one or two square feet at a time. I just want to be careful not to release too much brown stuff into the water column at one time.
