Should I get a chiller

I have had saltwater aquariums all my life. I have a little 29g nano tank that I am adding corals to. It has been up and running for over a year. The water temperature during the day stays at 79.4. And drops to 78 at night. I know that most corals say between 72 and 78 degrees is the recommended temp. Am I to hot for the coral to grow healthy. Thanks

 

you should be fine, i like to keep my tank at around 80

 

The reefs down here range from 70 to 85 throughout the year. Sudden changes in temp are what's dangerous, but most corals do fine between 78-82F as long as you keep it within 2 degrees or so over the 24 hr period.

my 60 runs at around 82 at present dropping to 80 at night
and everything seems fine

only ever experienced problems (short term) with corals when temps climbed above 84 for a period (corals started to close down, starting with LPS corals closely followed by leathers ) they all came around rapidly when I raised light unit to create more ventilation and facilitate better evaporation

 

Exactly. I've noticed that in the late summer months (diving from Jupiter south to Ft. Lauderdale) that when the water temp approaches 84 to 85, the corals don't open up as much, and algae starts to take it's toll. In the winter (if you want to call it that here lol) they do the same thing, except no algae blooms. They seem to look the best when temps are between 76-82. Last summer (late summer) we had some off-shore storms that caused some "wash-in" from the deep gulf stream, and we found temps at depth (75-100ft) as low as 67F. There were dead fish, corals, etc., everywhere. It was sad. I'd have to say that they are much happier being a little too warm than too cold. (pretty much like my wife now that I think about it!)

 

Your temps should be fine as long as they don't change drastically.
