What temp. did your tank hit today with the heat?

[Delphinus]

Before A/C my tanks would hit temps like mid-80's, high 80's, even 90 in a few extreme cases (ie. if I didn't get a chance to knock the halides off or something like that).

Last year I put in an HRV and A/C at the same time. Best investment I ever made for the hobby. Well, it was more of a "investment in order to stay in the hobby and not rot my house out from under me" - as within a year of the house being built I was getting mildew on the walls and ceilings - not good. The HRV put a stop to that as well as the "weeping windows" in the winter phenomenon.

And the A/C - well - it was that or a chiller - I gotta say, outside mid-30's, inside mid-20's - 'nuff said. Pricey maybe, but ooooooh so nice. But then .. it wasn't really much more than a chiller would have cost anyhow. And the tanks don't go above 77-78 anymore, ever. Thought about getting a chiller for the big tank if/when I ever get it running but the A/C is working out so well right now I wonder if I'd even need to go that step. Nice thing about A/C over a chiller is I don't have to choose which tank to put it on - the household ambient temperature regulates ALL tanks, FW/SW upstairs/downstairs.
