28 degree suitable

[Chichan]

Hi

I would like to ask the experts if 28 degrees celcius is suitable for corals, esp SPS?

Perhaps, for a selected corals? If not, what is the max tank temp?

28 is fine. SPS are particularly sensitive to temperature, so you may not want to let the temperature rise any more beyond that. Get a chiller if you plan for a SPS tank. However, other corals like soft corals and most LPS are not so temperature sensitive and can accommodate slightly higher temperatures. FYI, the ABSOLUTE MAX temp for a reef tank is around 30 degrees and most corals would not do well and die beyond this range. Personally, my tank temp is kept at around 28 - 29 degrees with a fan.

Thank you for yr advice. Yes, I do have a chiller which I maintain

at 28. Now I can be rest assured that I can proceed with sps.

28 is the max I would go. 27 degrees is more recommended.

Better colours below 28degC

I used to keep rics unknowingly at around 29-30 degrees. They started bleaching and shrinking. Now I am keeping my temperature at 27, the rics are huge and thriving.
