Reefing newb
I just set up my first salt water tank earlier this week and am waiting for the cycle to finish to add fish and corals. I've been monitoring everything water quality and temp and the water is always warm 80-84 F and I've left the lid open with a fan froze water bottle and dropped them in there but it doesn't get the temp to where i want it to be. 77 F. I am asking for your help, how to you keep your tank cool?
