Temp for SPS Tank

[Tommo]

It is interesting that we all keep the temps at different levels

currently i've kept a few SPS in my tank with 28-29 so far ok and it start to grow

30-30.5 degrees celcius is still tolerable by SPS. Lethal temperature for SPS seems to be 30.5-31 degree celcius, where you can notice STN.

+1..........me set my temp at 26.5-27.5 consistently.

IMHE...In 2 ocassion, firstly my chiller pump mulfunction and brought temp to 31.5 deg and suffered 3 collonies STNed. Second forget to on back chiller after maintenance and temp raise to 30+ deg. without any sps casualty.

think 28 degree is the max

for sps?

The followings points are taken from Reef Central:

SPS metabolic rates rise as temperature rises. They may consequently use more oxygen, carbon dioxide, nutrients, calcium and alkalinity at higher temperatures. This higher metabolic rate can also increase both their growth rate and waste production at higher temperatures.

Another important impact of temperature is on the chemical aspects of the aquarium. The solubility of dissolved gases such as oxygen and carbon dioxide, for example, changes with temperature. Oxygen, in particular, can be a concern because it is less soluble at higher temperature.

From my experience:

I originally set my temperature range at 26 - 28 and my ORP reading was 317

When I adjusted my temperature range at 25 - 27 and my ORP reading has improved to 400

[stevenkoh08]

i've maintain my temp at 28-29 and the orp reading maintain above 400mv and with 40 fishes

I'm setting my tank temperature to be 28degC with SPS....

Of course not those high end SPS....

Keeping those more hardy like birdnest, monti, etc..
