Maintaining a constant Temp

Viking Dr · 11/13/2011, 08:47 AM

I am having a bit of a problem with my temperature. It sits around 78 during the day with one of my 2 fans on(summer I use both fans). But at night it will drop 3 Deg. (more if I forget to turn the fans off, I know need a timer for those)I know for the fish this isn't a huge problem, but what about corals? I have no plans to have the corals requiring high intense lighting, but what about the others like candy cane, torches, Ancan? What kind of temp swings can these guys take.

My tank runs at 80-81 during the day. At night about 77-78. I have no issues and great growth from everything in the tank.

There is no solid evidence that fluctuation helps or hurts livestock.

I have found my system to be more robust with a daily swing.

My tanks go from 76-84*, depending on the time of day/year.

It has been my experience that swings are actually better than a steady temperature, allows the corals/fish to better handle any spikes that may come from whatever cause -- even a temp probe left out of the sump during a fall evening with the windows open. My tank ended up getting up to 89* by the time I figured it out, didn't lose a thing. "Greenbean" has done some real world research on this subject if you want more info.

If you ever go snorkelling, scuba you will know full well that currents of warmer/cooler water flow by constantly. I wouldn't worry about a few degrees variation.

I wouldn't worry about the 3 deg swing but yes I would put on a timer to shut off at night so u don't forget it on.

Ok thanks, FYI from my experience diving, thermal climbs usually stay at levels and don't mix for the most part. But there is always exceptions to the rule.

Look up some of Greenbean's research -- swings are the norm and not the exception.

With a Reefkeeper light and temp probe I have almost zero temp fluctuations. Sometimes I will change the temp manually on the RKL up or down a degree but that's it.
