I have been simulating a nasty massive storm the past few days. Turned up my Tunxe wavemaker and turned of my halides. Just actinics for 2 days and 8 hours a day.

even with lights out I think I peaked at 84. then back to 80 in the morning. I have a large fan over sump!!

Ya, the chiller is pumping away, tank stays at 79 all day. Which is good, because my condo probably hits 90 by the end of the day! I need a condo chiller for us!

Glad to report our AC is keeping everyone cool :)

We put our indoor thermometer/humidity reader out on our balcony on hot days. Yesterday, it hit 41 C in the mid-day sun. Was up at 4 a.m. this morning and it was 20 C out there. By 7:30 a.m. it had already climbed to 22 C in the shade. High expected to be 33 C here today, but on our balcony it's always at least a degree higher. Heat wave forecast goes into next week, but sure hope it cools down some before then. Can't stand AC on at night with no fresh air :(

my tanks are geting hit hard sence there all nano/pico, yesterday my 2.5 peaked at 90! and my xenia has melted but worest is i havent seen my firefish today:sad: , its at 84-87 with the lights on and my 1g is at 88 but the cleaner shrimp and coral seem to be ok, i wasent realy ready for the heat sence last year my room wasent that hot but the last two days were bad iam going to have to find some fans and hope they help or that this heat gos away soon or iam not sure what will happen:neutral:

I better check the temp on my tank!

*walks over to side of tank*
*looks at thermometer*
86.7

I usually just open up my stand on a hot day and blow a really powerful room fan into the stand - it's usually able to drop it by a good 4 degrees on a scorcher.

Holding steady at 81* as I have a good fan cooling down the sump, I don't like the 2gl a day top off thing tho :mrgreen:

With no one home, AC on, fan on sump, top proped open, My tank still hit 84.9.:cry: Since I am going on vacation for 9 days, i can't risk it. Finally broke down and bought a chiller. It will get to run for a week before I leave so hopefully i can iron out any potential problems, appears to be working good so far though.

Currently 29.9C with one MH light on. So I have just turned off all lights now. Room temperature is 30.5C using the same thermometer. I guess the evaporative cooling on my tank is making it cooler than room temperature by a bit.

I think the easiest solution for tanks without chillers and what not... just cut back your photoperiod. Turn the lights on in the AM , and off once it hits noon.. keep 'em off til later in the evening.. turn 'em back on again if need be. That's what I am doing.... 20g with 250w HQI in a bedroom and I am at 83-84... not too bad considering.
