Temperature

[sid2003]

For my 90 gallon FOWLR, what would be the best temp. to keep it at? I dont have a heater in the tank yet because I am wondering if I need it or not. I have been monitoring the temp and it stays around 72-75. Is that too cold?

Mine is also in the 78-80 range.
72 is too cold for most saltwater fish you'll find, and coral especially has a hard time thriving, much less surviving, in temperature that cold.
