80-84. Weatherman, what coral species displayed bleaching events at this temp? What is odd is that this is still within the normal range of most reefs.

Hereââ"šÂ¬Ã¢"žÂ¢s the reference.

For widespread, rapid bleaching events, temps around 31.5C (89F) seem to be the trigger point, but sustained, extended periods above 29C (84F) have been demonstrated to cause problems.

It should be noted that temperatures in the mid and upper 80s (F) may be common during the summer (or ââ"šÂ¬Ã…"œhigh-sunââ"šÂ¬Ã‚) season, but the temperature doesnââ"šÂ¬Ã¢"žÂ¢t stay that high all year round.

wow that was very sad I hope I never have to see that in person

Ah, ok thanks. I didn't see it in the article, but did it state the average temp year round for the particular studied reefs? I could see a bleaching event likely if say, the normal temp is around 80 and then sudden prolonged temps of 84. I can definitely see where 88.7 F temps could cause bleaching in any circumstances.

I've had issues with tissue recession in the past when I allowed my tank to get above 81. Currently I try to keep it in the 77-79 range.

After talking to Gavin at PAF (pacfic aqua farms) I now run mine around 75. When I was at PAF last I think the water was about 73.

Not too suprised, given Walt suggests that most of our Fiji corals are coming from mid-70's water:

I run my tank in winter around 76/77, in summer closer to 80/81.
