water tempature

sbkpklein · 06/04/2007, 07:14 AM

i have recently set up a 24 gallon aquapod with 150 watt metal halide light. without the light on... the tempature is 80-82 with it on it goes up to 84-86....is this going to create a problem when i start to introduce fish and corals...

Yes. In the summer it's going to get worse, and you need to take measures to lower that temperature...be it keeping the a/c on in the house/apartment, or blowing a fan over your water surface. If you don't have your lid open, open it and run a fan. Many light fixtures have 2 fans keeping the bulb and unit cool.

Your temperature should run about 80.

Corals bleach and die around 85 degrees. Hot water can't carry enough oxygen for fish health. Etc. You need to fix it before you add any specimens. If you can't fix it, you may have to consider going to T5 lighting, which is a bit cooler.

And run two thermometers of different type: the discrepancies in thermometers are sometimes alarming. If yours, for instance, is reading 2 degrees lower than it is, your problem is worse than you think; if 2 degrees higher, it's not as bad as you think.

I've got a 150w halide over my 10g tank and temp would go up to 85. I added one fan in my canopy, angled towards the water surface, on the same timer as the light, and the temp stays right on 80. Not sure how much flexibility you have with one of those aquapods though, with adding fans or whatever.

well so far this summer i have not had any die off do to heat and my tank gets up to 88 when its 90 outside but last year 86 i was killing every thing now the ac is on all day keeping the house at 75 tank at 80. but in you case the fans would be best. ice cap sells a variuble spped fan the goes fster the hotter it gets and is very quite

86 is going to be a lot of trouble especially when the summer starts heating up. You will definitely need to add some fans to keep the water cool.

chances are its going to be very difficult to keep your tanks temperature consistent while running powerful lights and it being 90+ degrees outside

to help combat all the heat, try reversing your photoperiod. have your lights turn on early morning (pre-dawn) and have them turn off when the temp starts to pick up outside.

and like everyone else has mentioned, a fan does wonders

For emergencies, I have 2L soda bottles 3/4 filled with ice and frozen in my freezer. I can add them to the sump, should my temp get up over 86*. 1 bottle will drop the temp about 2* in an hour.
