Hey Ivy-I agree on the room AC....if the room isn't hot...the tanks don't get hot.
We resorted to a small window AC in our kitchen with a couple of FOWLR (with a coral or two in them...
) closed the room tightly and today the temps look OK. The 120g was at 87 yesterday and today is at 79-80 and the 50g was at 88+ yesterday and is at 82-83 today...both have fans blowing on them also today as we didn't quite realize HOW hot they actually were until we got more thermometers yesterday. Thank God for the chiller on the reef tank or it would have hit low 90's as it did last year and we would be picking out shrimp bodies...(never buy a stucco house with lots of windows....ARGH! Gets smokin hot inside)
