I'm not really sure whats happening, the tank did get up to 86 the day we started to tear everything out of the living room and then I switched the light cycle to night/early morning so the tank could be covered during the day without heating up ( it never got above 84 again).
At some point the sump room started reeking of coral sex (kind of distinctive once you've smelled it once) and the skimmer shut down for 2 days.Unfortunately I wasn't in a position to do any water changes.
A few acros are losing tissue, the monti caps are bleaching and looking decidedly unhappy and the digis are losing their growing tips.
I bought a bucket of salt from Bob today ($80
) and I will start water changes as soon as the paintings done tomorrow night/wed
