Oopsy - I should have made myself clearer than complete mud, sorry...
The tanks that have the a/c blowing on them are the 2 tanks that still have heaters in them.
Everyone else w/out heaters now are in completely different rooms than the a/c.
The reason I took the heaters out is cuz wuv told me to. lol
Actually - i have had lots of issues with lots of my fish. I'm trying to make them a little bit more tough-skinned, I guess, in that they can go thru some minor temp fluctuations. We'll see how it goes.
Besides, it's now 90+ degrees here today with full blown humidity and they're all at 80 degrees or so anyway. It only cools off a bit at nights, so the heater just isn't really necessary. AND, for the same reason tops just aren't necessary around here either. It's just much appreciated round these parts, especially since I live in Wisconsin, where we LOVE to eat brats, cheese and consume LOTS of beer. lol
