Temperature Limits

[desert fishy]

I have a 75 reef w/ref. My temperature is varying from 74.5 to 76. Is that too low? I know I'm lucky to have low temperature issues, but I've heard varying opinions on what is acceptable.

i have heard a good temp is between 77-80ish
mine runs 79-80 and it has worked great for me
