As living in a tropical country, the ever creeping up temprature is a hash relity.
Finally coughed up some serious dough and bought a chiller. Unfortunetly it can only set temprature in in 1°C range. can't on in 0.5 ranges.

So currently its set to 27°C and it will creep up to28°C before it kicks in.(Would love to set at 26.5°C and goes to 27.5°C)
I think one of my two anemones don't like when it gets near 28°C range.
In Sri Lanka we have an electricity crisis and when you use higher amount of units your electricity bill shoots up like crazy. So trying to keep my chiller on as short as possible.

What do you guys think the highest possible stable temprature range for a reef tank?

According to this article, you'll be fine up to 29* C.

"The most rapid growth of most corals is generally around 27°C to 29°C (80.6°F to 84.2°F) (Barnes et al., 1995; Clausen and Roth, 1975; Weber and White 1976; Coles and Jokiel, 1977, 1978; Highsmith, 1979a, b; Highsmith, et al., 1983)."

Wow that was a bit unexpected!

So far I have 2 green BTA and 2 brain corals. For fish clowns, anthias, similar damsels and such Sri LAnkan sourced stuff.

While I agree that you may be able to keep some corals up to 29 C and that fastest growth will occur between 27-29 C, that doesn't mean that you should do it. Just like corals will grow faster at an ALK of 12 dKh, you are now attempting to walk the proverbial tight rope.

I would recommend the 26-27 C range, then if power goes out, you have more time until your tank gets to the unsafe range. While 1 degree C isn't much, it may buy you an extra 30 minutes to an hour. IMO, the 26-27C range is that sweet spot between being to cold (22 C or less) and to hot (30 C and warmer).

Wouldn't it be better for the fish and corals if the tank tempratures goes from 28->29 or 30 than from 27->30. It seems it would make less of a shock for the fish.

No, it would be better if it never got that high. Fish and coral can take temp swings of a few degrees C without any problem. If the power were to go out and you kept your temp at 28-29 C, then it wouldn't take long for your tank to exceed 30 C without quick intervention. It will take a lot longer for your tank to go from 27 C to +30 C than from 29 C to +30 C. A good mid range temp to shoot for is between 25 C and 27 C.

Again, you can run the higher temp, it's just harder the closer you get to the extremes. Other things than fish and coral grow better at the higher temps in your tank as well. Algaes, bacteria, and harmful organisms like higher temps also.

Build the tank around what you are given. Its advice you will hear often on freshwater forums where changing water chemistry is the exception not the rule, and people use dechlorinated tap more than ro/di.

Stay away from deep water or temperate species of fish and corals.

Shallow species of sps and photosynthetic gorgs would be my selections. Pick fish that are also from the surf zone. With fish O2 will be important at these elevated temps. Plan your circulation pumps accordingly. I would use gyres, they can get almost to the rim of the tank, create massive surface agitation all while not making that gulping sound a power head will.

Lots of folks are at 27-28 with out chillers here in southern California and the fish and coral do fine. We also have huge electric bills with scaled pricing.
If your anemone like it cooler then it will have to adapt or you will have to spend more?

Good luck!
 
Thanks guys.
I don't have to worry too much about 30+ at power lossas. The maxmium water temprature might go during summer is 31 or 32.But a mroe normal range would be 29-30. These days it sits at around 28.5-29 without chiller.

I will see how that anemon do. It maybe from deep waters becasue it don't like the light one bit either. I stays at the very bottom of a rock and poke out a lot mroe only during low light conditions. Mind you where it is siting there can't be mroe than 30-40 PAR.
 
I think ideal is around 78-80. I'm not super concerned until it hits 84 because then something is definitely wrong in my apartment or with my system since it's set to maintain at 80. I'm pretty sure 84 is the highest you'd consistently see success in a reef (and then I'd still be anxious). I do think the main thing is stability, so that's why I chose a temp and set everything to maintain it.
