81 to high for sps reef?

[Chicago]

just noticed that my neptune probe for temp was off by 4 degrees..

got new one that showed tank at 81 not 77.

have lost some corals in the past when i thought temp only went up to 79. wonder if temp increasre to actually 83 did damage

thoughts

thanks

i ran a sps frag tank for a year that would max out at 85 at the end of the photoperiod on a summer day.... never had any troubles. i will admit i was knocking on the door though

It is more of the temp swing than the actual temp (within reason, of course)

[Chicago]

that is what i figured. thanks ..

My tank runs at 83 normally, with swings to 81-84.5 and I don't seem to have any problems.

Try to keep your tank in about a degree swing and you wont see SPS stressing from the temp changes. Some folks try to keep it to 1/2 degree but that is very hard even with expensive controllers. Whoever said 85 is fine, I agree that my tank did get there in last summer pre chiller install and never had a problem. Coralline grows like crazy at the higher temps too, if thats of interest.

Actually, higher temps of around 82-83 will result in increased coral growth rates, as well. Of course, growth will curve off the higher up you go, halting completely in the upper 80's.

you can also bleach out your coral at high temps. i dont think its a positive thing honestly, i have noted increased growth at higher temps but colors bleach out and eventually you will see a tissue recession.

[Amphiprion]

Like I said, it depends upon what temp they were kept at under normal circumstances. My tank goes from 77-80 degrees in the winter, to 80-84 degrees in the summer, with various spikes at any given time. Being in the south, I would say the average is around 81 (maybe 82) since it stays warm for a while. If you maintain your temp at, say, 78 most of the time and suddenly it spikes to 83 or higher, you will have quick bleaching problems. Tanks maintained at more natural temps, say 82, tend to tolerate swings much better.

No problems here, I run it at 80-82F everyday with no problems related to temp.

[Chicago]

problem i see with running at 82 or 83 is that you have not saftey zone... in other words jump of three degrees form 78 to 81 is ok but jump from 83 to 86 might cause sps to bleach or other form of disaster?

[Amphiprion]

If maintained at those temps, your corals are far less likely to bleach under sudden jumps as you describe.

I run mine 80.5º constant so 81 isn't too high.

The biggest thing is not to have huge temperature swings throughout the day.

Last summer mine ran at 85 consistently near the half part of the day till lthe lights turned off. I had 0 issues and to be honest, my growth was phenomenal. I'm running now at 82 to 83 and it's hard keeping up with the trimming with my busy schedule.

Ditto

There are some folks who also think that along with the reported increase in growth at high temps, the skeleton is less dense than at cooler temps. I've never noticed this myself.

Mine swings from 79-81 through the day.
