AC is out, aquariums are almost at 90 degrees (except the one with chiller - thx God for chillers!). I've turned out the lights, adding aeration, I don't have any clip on fans - anything else I can do to cool them down?
Thanks for all the comments and support. The tanks all survived and fortunately the ac was just acting up for that one hot day. 'course by the time the maintenance guy got to my house at midnight, the ac was cooling again and he wouldn't even look at it! Been fine since though.
