I bought a frag of ORA Hawkins echinata about 5 days ago. I just returned home from work and found it had RTN'd. It's about 100 degrees in the Chicago area today. My house has the A/C running but the tank is in the low 80's. All my other corals are fine. Are Hawkins echinata particularly temperature sensitive?

Couple weeks ago my tank got up to 82.5 a couple times due to the heat and it seems to be doing fine. However being transfered 5 days ago coupled with "low 80's" temp might have done it in.

I don't think low 80's is too bad. It has been really hot here and tank is getting up to 84-85 during the day. It is really stressing me out, but Hawkins is still looking good. Hawkins can be kind of sensitive to dipping, so if you dipped it, that may be a possibility. How are your other corals doing?

Was it a fresh cut frag? Or was it healed over for some time?

how hot is the house? I ask because here in michigan it is like 96 today and going to be over 100 and my house is not cooling like it used to have the ac on all day and it is 83 in the house just when I thought I didn't need a chiller
I dipped the coral in Revive for about 10 minutes during acclimation. That was on Saturday and it didn't RTN until yesterday which was Wednesday. It was officially 99 degrees here yesterday but our house is cool with AC. It appeared to be a healthy frag and well encrusted on the ORA plug. I actually observed it at the LFS 1 week before I bought it and then came back to buy it. All my other corals are fine and my parameters are good. I'm stumped by this one. My best guess is temperature because aren't echinatas deeper water corals? I had it in a spot close to the bottom. My tank is 24" in height. My lighting has 3 x 175 watt MH with 2 160 watt Super actinic vho's. Even with 175 watt halides I can grow many SPS and clams right on the sand. The LFS told me I'd get better overall color on this frag with it middle to lower in the tank.

Dipping was most likely the cause of RTN. I lost a frag of the Hawkin's from dipping it in Revive for 2 min. It looked fine at first and started to RTN a few days later.
There's a couple threads about negative effects people experienced when dipping "smooth skinned acros." One of the more vulnverable one's unfortuntely is the Hawkins.

+1....like nvdiz just stated, there are a bunch of threads here on RC that have experienced RTN after dipping Hawkin's. It seems like a very sensitive coral to dips.
+2 Echinata's seem to be very sensitive to dips like Revive and CoralRX. I usually only dip for a minute or two and in diluted solutions. You could generally see most bugs because of the thin branches on the corals.
I keep mine in moderate light about mid way off center to my 250 watt 20k Ushio MH.

My sps tanks have always ran 82-85, with no problems as well.

In South Florida we get the temps you guys are getting 6 months out of the year. No chiller here. We might have better suited AC units though. I guess thats besides the point though. Tank temp is tank temp, regardless of room temp.

Revive is only supposed to be used for 5-6 minutes....
