Optimum Temp for reef tank

[calla]

I have snails, urchins, lot of hermit crabs, and a couple mushroom corals. What is the best temperature to get the citters more lively?

 

[reefreak29]

they say 78 to 83 degrees for a reef tank

 

[fedukeford]

80 +/- 1 or 2 degrees

 

[catawaba]

stable at 80-82 IMO

 

[oceanists]

I think 76-78
Heat will kill Zooanthalaxe
This is the problem with global warming and the coral reef.
76-78 is optimum.

82 gives good growth and leaves a little room for error....but if it hits 85 you can expect ill results.
