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?
This has happened to me twice now in two years...I just kept doing water out and putting it in the freezer to chill. Also froze water in a gallon jug and floated like an ice cube... Everything made it...hope you have the same luck.
Don't know the locations of the other tanks or the inhabitants, but could you move everything into the tank with the chiller? Or plumb all the tanks together so they all get chilled with the chiller?
