What's the best temp. range for sps?

[woogie]

Ok, besides NO Range. I don't have a chiller, and have had a hard time with acroporas. Liveaquaria.com says 72-78, but I've heard 80-84 is better from some reefers.

Any thoghts from you successfull sps keepers? and how wide a daily flucuation is acceptable?

Thanks!!!

Higher temps like 80-84 will give you faster growth, but you risk bleaching your corals if you temp increased a degree or to, plus higher temps increase your chance of disease outbreaks (bacteria etc. grow rapidly under high temps) I keep my tank 78-79. Anywhere between 74-80 is fine. I'd try to keep fluctuations to within 2 degrees if you can. I doubt that's what your problem is though. What lighting do you have and how's your water flow and tank parameters?

78-80 is my range....

[LBCBJ]

Also, acropora are very sensitive to temperature changes.

80º with minimal fluctuation during the day.

ditto for what dean said 78- 80 the less fluctuation the better

close to 80 as you can get it. Tanks can do ghosty temp spikes if a stray sunbeam wanders across the room on the first cloudless day in a month [given seasonal precession] and you want some leeway, since 85 is lethal.

Thanks guys. I didn't know that 85 was lethal.

LBCB, my water parameters are pretty standedard (according to test kits), and I have about 700 watts of lighting, but my temp changes from 78-83, a 5 degree temp change from night to day from the MH lights. i think I'll add a fan to my sump b4 trying to buy another acro frag. I assume it's the fluctuations that killed the last one.
