Hello all,please tell me what is the ideal temp for a 90g I hope to finally set up in July,I hope to have reef with some softies and maybe a clam or two if I can get the lighting(MH) plus fishies... I have an 16ft large sliding glass doors about 10 ft away from tank that I plan to put window tint on asap to block the sun and then a mini-slpit AC about 10 feet on the other side.(it's kinda blowing right in the direction of the tank) which here in Florida, any ac is good. I decided to go ahead an fill the 90g tank that I have and take temp reading for awhile, after 24hr Im reading about 70*-72* without the lights. My concern is that after I add the lights my temp will go high and I will need a chiller(hopefully not) too much $$$ any thoughts? Thanks!
