Half bleached RBTA after temperature swing

[ojonas81]

I have had my RBTA for a couple of months now and it has been doing great so far. Settled in after a few days and have not moved since. It is eating well and seem to thrive.

A couple of weeks ago, after a hot spell here, the tank temperature hit 86F+ which is no good for anything in the tank. Went out and got a chiller (should have gotten one way earlier). Unfortunately, the "warmest" setting on my chiller was 82F so the first day I had to get the tank down to that temperature (would have preferred to cool down in slower increments). Anyway, after a couple of days I was down to where I wanted my temperature to be, 77F.

however, after all this I have noticed that my RBTA (and a few other corals) got pale and some of the tentacles was almost see through with a red tint. Is this because of the stress caused by the big temperature swings and will it be able to come back? It is still eating well and looks like it is doing good (besides the bleached appearance).

Checked my parameters last night and they are:

Sal: 1.024
Alk: 9
Ca: 460
Mg: 1450 (little high, don't know why)
Ammonia: 0
Nitrite: 0
Nitrate: 60
Ph: 8.1

Anything else it could be?

I had the exactly same thing happen last July to my RBTA. It was almost completely white after being a dark maroon. I kept the water very stable and fed small pieces of table shrimp every other day and it made a speedy recovery.

Good luck!

Thanks!

I hope mine will come back quick as well. How long time did it take for your to come back?
