Tank temp is 73 degrees, i have my halides on, 3x250W heaters on, and trying to get it up. I've got all my powerheads at the surface sucking air bubbles into the tank to help with O2.

Is there an issue re-heating too fast? Temp swings are bad, i just want it in a normal range so i can hopefully save whats left. Should i blast this up to 75-76 then slow it down? or just ease it up the whole way?

So far: flame hawkish, coral beauty, shrimp, bunch of hermits, all dead. Coral is an unknown right now, but not looking terrible, i'll have to see what happens in the next few days. My tang is having a rough time, on the sand gasping.

Bring the heat up slowly. But the issue is the lack of oxygen.
Take the tang out and any other fish who are suffering and place it is a large container with tank water and place a bubbler in the container. The deaths are the result of lack of oxygen.
