Temperature Swings: What is common for you?

Hurgoth · 02/22/2006, 12:36 AM

Hey All,

I was wondering what is a typical temperature swing for you on a given day (summer/winter)? I do not run a chiller. Currently my temp swings are usually as follows:

Winter: 74 morning (lights on) / 78 night (lights off)

Summer: 80 morning / 84 night

Granted, I use digital thermometers (but I use two, 1 in sump, 1 in tank).

Are these temps bad?

I would have to say no they are not too bad, I prefer using a chiller that way my water temperature doesnt fluctuate as much. personally I think 84 is too high, but you will find many people that would say that there is not problem, just like I think 74 is too low too.

In my tanks, if the temperature drops below 76 degrees my corals start closing a bit, while if I keep it between 77 and 79 degrees they are fully open.

I hope this helps or answeres your question

Winter: 80Ã‚Â° constantly, with the occasional 81Ã‚Â°, when leaving a halide on too long (getting a new timer)

Summer: 82Ã‚Â°-84Ã‚Â°

Your temps listed are not bad, but 4Ã‚Â° swings are. Maybe invest in a fan, or a controller for your heaters. I have no chiller, and use an Aqualogic controller. Turns my heaters off at 80Ã‚Â°.

Depending on winter or summer, my temperature swing between 79-81 running on a chiller/heater.

79.5-80.0 and thats it. Using an AC Jr. temp controller and its one of the best things i've done for my tank.

mine only swings 1*- 2* within a 24 hour period......any more than 5*swing in 24 hours can be dangerous

78Ã‚Âº when the lights go on. 79Ã‚Âº when lights go off. I guess it takes a lot of energy to heat/cool 300 gallons of water.
