Ideal Tank Temp

[smallmihai]

I've seen answer from 75-85 degrees. I try to keep mine around 77 but with this hot weather Ive been having it go up to around 81-82 in the day and back down to 77 at night. Whats a ideal temp?

I have mines at a 78

78 to 79.

I think 76-79 is the best, but its all about stability you dont want it to fluctuate to much. 85 is pushing it depending on what corals you have

 

[smallmihai]

Would a 3-4 degree varition between day and night be considered unstable?

Yes, you should only have a 2 degree swing at the most. 3-4 degree swing is pushing it and you corals won't thrive in the long run.

and fish are more prone to stress with a swing like that. Get a controller and a chiller to control your temp. I use controllers on all my tanks and keep them at a steady 78.1 24-7

I only have a 12 gallon nano tank so I dont know if I can justify the cost.

put a fan over the tank that should help

Ive bene doing that with a desk fan about 5 ft away. But temp still rises

Yes I agree.. it keeps the temp more stable

If you can try to keep it closer to 77-80 you will be better off. Like everyone says a fan over it will help move heat away but will also cause you to have to top off more often.

My tanks are at 80.

Summer, 78-80
Winter, 76-78

I keep mine 80-82 with a controller and fan. I have a 28 jbj nano.

Having the fan 5ft away won't really do much. The point of the fan is to increase evaporation, which in turn causes the water temp to drop. Try something like this:

EDIT: because you point it directly at the water.

You don't want your temperatures varying like that, if its a reef tank, aim for around 78-80, if its a fowlr, you can go a lot colder depending on what regions the fish come from.

usually i go 77-78 in winter and 78-80 in summer.
