Temperature Variation

I started this poll up because I lost a sally lightfoot crab I bought a week ago. The only thing I can come up with is my temp. in my tank changed as much as 4 degs. in a 24hr period.
My MH light really warms up the water.

I decided to take a fan I have and blow it over the top of the water. Yesterday I was able to keep it down to only 1.5 deg change.

So then I was just wondering what is the average amount of others, how much does your tank change in one day

1 degree here.

Then let me add this. Any suggestions on how to keep your temp. down.

I have two 3" muffin fans mounted in my hood. Now this circulation fan.

Hehe....that is the question isn't it. You could buy a chiller!

I have MH lighting which does warm the water up some. I have made a compromise with my tank. I would like to keep it cooler but....I keep it at about 79.5F. I run my heater and it does run a little during the day.

Without the heater, the tank fluctuates about 3 degrees or so within 24 hours (due to the lights) so I just adjusted the heat little by little until there was very little change during the day. It stabilized at about 79 - 80. I am going for stability. It does not give me wiggle room if something goes wrong tho. But I am home most days and can keep watch.

Thanks for the reply. I thought about the chiller, but me and my tank live in an apartment. I've herd a chiller is like an AC unit that really needs to run outside. I keep the temp down as much as I can with the apt AC (I run that about 72o)

Wow your still running your AC? Man I got my furnace kicking right now.

I run fans with my MH lighting and have a swamp cooler for the summer months. Tank is in an interior corner with no exposure to sun light.

Cool poll. I'd be curious to see if there are people with pretty big swings out there, you should add a 5-10 degree option.

Open top and micro chiller here.

My heater is set fairly low in an attempt to compensate for a relatively big halide that heats my tank pretty well. As a result my swing is pretty big. I suppose I could turn my heater up during the winter now that you have me thinking about it. hmm...

Matt thanks for the compliment on the poll. With the fan on now I was able to keep the swing down to one deg. last night.

Just like it was mentioned it's just a matter of tweaking the heater. I like to get the tank cooler, but now it's averaging 80o.
