rise and fall of tank temps

hoginme · 08-21-2001, 09:39 PM

My tank temp drops down to about 79 deg, at night when the MH and flouresents are off and rise to about 82 deg when they are on. My MH is a foot above the water I have one fan blowing outward to help keep it cool and i have good surface agitation to help with evaporation of the tank. My ? is, is this temp flux going to be ok or will I need to do something about it and what? I cant get a chiller right now. Thanks for the help.

Hey Hoginme, 81-82 is fine for a reef tank with adequate circulatiom, I would set the heater up till it almost comes on when the lights are on and it should keep the temps fairly stable

I run my big tank at 82; having a heck of a time keeping the temp constant in my nano at work which sits right by the heating/cooling vent. (sigh)

As long as your swing between day and night temps stays consistent and doesn't drop lower than it is now, I think your tank will be fine.

Our tank is about 79 in the morning and 81 in the evening. Yesterday it crept up to 83

. We have been lucky enough to have our AC off for about a week now, but it was still getting a little stuffy in here. I'll up the therm. temp to 79.5. Maybe this will help our swing.

Man, wouldn't that aquacontroller have been nice yesterday!

I don't think 83's a big deal Brooke; I know people who run their tanks at 84 but boy, that's pushing the envelope to me.
