What temp?

what temperature should i keep my reef at it stays at room temp (75) but some times my mom turns off the a/c and it getsto 80 (not very often) or it's close the door and at winter it gets to 65-70 what should i keep it at what is a safe range of temp change

 

Mine stays 78-80

 

Keeping the temp constant is the key. 80 degrees is the "norm", with exceptions of course, but 80 degrees is in line with the ocean. You can use a small heater and set it at 78-80 in winter then in summer (when mom may turn off air) set it to 76.

 

mine stays at 76.5

 

I would get a heater and set it at 78-80. Buy a small clip on fan from wal-mart and blow it over the water when the ac is off and the temp starts rising. But IMO a swing of 78-80 isn't horrible.

 

Mine stays at 80 during the day.. I have a clip on fan like bmshehan said, I have it kick on about every hour for about a half hour just in case things get too heated... Oh how I love timers...

 

78 is where i keep mine

 

Better get something to stabilize that temp or your going to have stress on your livestock. 78 to 79 is a good temp.
