sps tank temp ?

What is the best temp to keep an sps tank.

 

[JOSHUAB]

mine fluctuates depending on the time of year from 77.4F to 81.9F, everything does junst fine w/lots of growth.

I keep mine at 78 degrees +/-1

82-83 for mine . I was running it lower but my chiller ran too much . I have seen no difference that I could say was from temp.

79-81 depending on time of year.

You will get SEVERAL different values for appropriate temperature in our aquariums. It is an ongoing debate in this hobbie with some favoring 78 and others as high as 85 or more.

Personally, I think stability is the key. Acro's and other stonies do not like change and especially rapid change. I aim for less than a 2 degree temp change per day.

I favor using natural reef temps for my aquarium.

79-81 is where I run mine.

I was trying to keep it at 76, but after installing my uv it's been holding steady at 78.

Thanks guys I have set me acII to keep my tank at 77 +- .01.

Some survive temperatures over 100 F and don't bleach. Others see winter lows in the 50's. A reef in the FL Keys might hit the mid to upper 80's during the warmest weather and the upper 60's during the coolest weather. The reefs around Hawai'i average about 80 in summer and 75 in winter. In Belau the summer temps might be in the mid and upper 80's whereas winter temps are in the low 80's. In Fiji the warmest weather might bring 84 F and coolest weather about 78 F. In some places the temperature is very stable and changes little over the course of a day (maybe 1 F). In other places it is much less stable and it might change 15 F or more in 10-20 min.

Corals (including Acropora) lives in all of these environments. It's up to you to decide what you think is appropriate.

Since most of our corals come from the Indopacific and that is the center of coral diversity, I tend to more-or-less follow the temp. regimes I see in that region, though I shy slightly on the side of caution in terms of high temps. as I know that corals are close to their upper thermal limit in many environments.

So, for my tanks: winter 79-82 F, summer 80-84 F. I've never had problems if the tank hits 85-86 here and there during the summer (this may not be so for corals acclimated to cooler temps). At about 87 and higher is when the corals start to looke "wilted" in my tanks. I try to keep the temp. at or below 84 during the summer though.
