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

Mine maxed out at 81. That's with 3 250w DE MH on all day too. Very happy with that. Tomorrow though will be a challenge since it'll be even hotter in the Lower Mainland. May have to use my new AC unit after all.

Didn't budge past 78F with 3x175w MH - I love my basement =)

must be nice. my tank every day goes from 80 in am to 83 in pm with 3 400w's. i have central air in the house so the outside temp doesnt effect it. i have debated on getting a chiller but nothing in the tanks has evered showed any signs of suffering.

It's been hella hot here in Calgary at times already this summer, and I live on the top floor of a condominium complex. The highest I've seen my tank is 82.5. Not too bad I guess.

82.5 isn't that bad. Last summer in my condo mine peaked at 89F. This year my tank is in the basement, where I can take the lid off when it gets hot. Temp range has been 78.5 to 79.5 all day and night.:biggrin:

88 at 10pm a few weeks ago before I got my chiller.

Its 27 in my apartment now, and its just after 9am.

84.8 with 2x400w halides.....that includes having fans on the tank....ugh...I think a chiller is next as it's only getting hotter

i was at 84-85 on 2 different tanks yesterday

I invested in a chiller last winter as I had a lot of dead corals last summer & fall. I have it set to come on if the temp reaches 80.5, so far so good.:smile:

83 degrees using 2x150W over a 50g. I suspect that may go up this summer, if we get a true summer :), so I'm going to mount my MH fixture from the ceiling so that I can increase the distance between the fixture and the tank.
When I had the Corallife 1x150W on the tank temperature increase wasn't a problem.
