29C, so...82. Completely closed system... finally occured to me today that I could open up the cabinet underneath so that some air could circulate over the sump, that may help. The temp inside the house, on the other hand... a whopping 34C today. It's HOT. Glad I've got LED's instead of MH's...hate to think what the temp would be like otherwise. o.O

I came home today and kissed my chiller. Temp was 77

I hugged my chiller this morning :lol:

:lol: :lol: :lol:

I didn't want to chance a tank melt down come summer so I moved my upstairs tank to the basement. My main tank is already in the basement, although just running heaters and the basement usually cold, I did notice my tanks hit 79 yesterday. Yiks! Or so I thought. Since I keep them at 77 usually.

So it reminded me to turn down the heaters come summer. :mrgreen:

Wife bought central air for the house last year (and tank was part of the reason), tank's 79°. She got another kiss from me.

as long as i keep my sliding glass door open, i'm good. when nobody's home and the place is locked up, the RK2 shuts the light down. thank god for temp controllers....(thank you Digital Aquatics) i will never let a prize aquarium live without a temp controller again. a chiller is nice, a temp controller is awesome...both is better. scratch that...ESSENTIAL. i insure my belongings....$2,000 in livestock is insured...remind me to review the insurance policies of the livestock i'm responsible for. shameless plug for reef computers: GET ONE! if you have thousands invested in an aquarium, buy an aquarium computer. the peace of mind is worth thousands....all you have to spend is $400. if not for the sheer dollar value, find comfort in the fact that you're sparing live animals.

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.
