80 to 81
02/12/2006, 09:21 PM
I try to keep mine at 78-80 but it's usually 80-81
02/12/2006, 09:35 PM
Hmmm...I keep mine at like 75. Too cool?
02/12/2006, 09:36 PM
yeah i think i bit too cold, mine goes from 79.5 to 80.2 now that i have the controller before was pretty bad

76 - 78
And it's real easy to keep track of now because I got one of those Pinpoint wireless thermometers. Really cool toy! It will handle up to 4 tanks, I have 2 on there now. :beer:

78 - 81.4

Try to keep mine at 78

81 right when the halides go off, 79 in the early a.m.
02/13/2006, 07:41 AM
I shoot for 78 also. Though my basement is heated by woodstove, and if we don't keep up with it on a really cold night, it will dip to 76.
02/13/2006, 07:49 AM
77 to 82
80-82 in the 120; 77-79 in the basement.
02/13/2006, 08:50 AM
I'm 81-83. Could it be too warm? Some of you are real cool.
I'm guessing everyone here has a chiller. Anyone know approx how much power is consumed to bring the temp from 80 - 82 down to 78 - 80. I simply never thought to run it cooler, but my Chiller seems to work flawlessly on my system, I could easily lower it.
Maybe this will solve ALL of my problems:) Yea Right.

no chiller on my tank. I have one, but its not hooked up. I know ill need one in the summer though.
my heater is blazing away trying to keep the temp in the 76 range. but thats also due to the fact that we are cheap college students and keep our heat set at 61 or 62 b/c heating our house is expensive for us.
02/13/2006, 11:44 AM
No halides, no chiller.
Kind of hum that along to the tune of Bob Marley's "No Woman, No Cry"
House is at 70, I heat the tanks to 76 with no lights. Lights bring them up a degree, sometimes two.
02/13/2006, 12:13 PM
25 to 27 at my house.
02/13/2006, 12:31 PM
no chiller just two small fans, im looking for a chille but will be hunthing for a nice buy
02/13/2006, 02:29 PM
low of 78.5 high of 80.5

Leave it to Marcelo to post in Celcius. :lol:
02/13/2006, 04:13 PM
The numbers were getting too redundant :D
02/13/2006, 05:53 PM
Yeah, I guess that might be part of it. I have PC lighting and they don't really generate much heat. So I can keep my tank more or less at the temperature of my apartment. But it still sounds like I'm a little low.
02/14/2006, 06:18 PM
79 to 80.9, then the chiller kicks on.

It is interesting to see that the average temp of many of the tanks kept locally seem to be lower then I expected and am curious as to the reason. I know there have been many heated arguments on RC over the years as to the proper temp for a reef tank and it certainly is not my intention to start another one here. I would however be interested in hearing peoples reasons for an average that seems to be around 77-79.
I tend to keep my tank in the 81 to 83 range and maybe even a little higher in the summer. I based this range on several articles I read a few years back of which here is one if anyone is interested. http://web.archive.org/web/20020610144845/www.animalnetwork.com/fish2/aqfm/1997/nov/features/1/default.asp
And here is a quote from another:
"These authors took measurements from over 1000 different reefs, and determined the physical and chemical limits statistically.
The temperatures they found (Converted to Degrees Fahrenheit):
Averages: Minimum = 69.8Âº; Maximum 85.1Âº; Average = 81.7Âº(this is the average temperature of all coral reefs).
Minimums; Lowest = 60.8Âº; Highest = 82.8Âº; Average = 76.4Âº.
Maximums: Lowest = 76.2Âº; Highest = 93.9;Âº Average = 86.4Âº.
Some extremely warm and saline reefs were noted.
Extreme Reefs (Maximum Weekly Temperature in Deg. F; Salinity in ppt)
Southern Red Sea = 89.1ÂºF - 91.2Âº F; 38-40ppt.
Central Red Sea = 88.7 ÂºF - 89.1Âº F ; 40-41 ppt.
Northern Red Sea = up to 88Âº F; 41-42 ppt.
Those of you with Red Sea animals may well wish to alter the temperatures of your reefs."
I hope some find this article as interesting as I did.

Way to kill a popular thread, Eric.
You didnt Kill It, just fueled the Fire a little. Good Data. I know I've seen that before, I'm sure you can get good arguments from both sides.
At first I thought everyone just had great Chillers and/or high electric bills. I'm sure everyone here has a high electric bill, but it seems a lot of us are running tanks without halides and struggling to keep them as warm as 77 deg with heaters.
This time of year is a battle between heaters & chiller in my tank. This thread got me to lower my heaters by a degree, and probably save a lot on my electric bill.
02/16/2006, 10:16 PM
Electric is one consideration, but as I recall lower temps allow higher dissolved oxygen concentrations. I'm also trying to reduce the rate of evaporation.
02/16/2006, 11:21 PM
Good information Eric. You just answered everyones questions!

I would however be interested in hearing peoples reasons for an average that seems to be around 77-79.
1.) Yes, electricity is my primary concern, that's why I've resorted to keep the temp a little lower than what would be the norm. My electric bill went down average $25-$32 since I lowered my heater to 77 degrees, lowered my MH photoperiod to 5 hours and switched 4 Maxijet 1200's (20W each) to 2 Tunzes (15W each)
2.) I keep my tanks at minimum 77 degrees because I need the extra 5 degrees of safety for when the halides go on, or for the uneventful warm spell. I don't have the luxury of a chiller, and would probably never be able to implement one in my condo due to space reasons, I resorted to keeping the tanks cooler for the reason stated.
3.) Cooler tanks equal slower metabolism and growth. Cooler tanks harbor or slow down bacterial or parasitic infections. Higher metabolism tanks (warmer) need to be fed more often, cleaned more often, maintained more often. I'm LAZY.
Let's not start a debate, let's please just state personal opinions for the temperatures chosen :D
Oh yeah, I'm starting a thread too, but it's on salinity. Doesn't salinity have a correlation to temperature?
02/17/2006, 01:25 AM
I don't run a heater, lol. it usually runs at 79-84 and I know that is a huge variance. I don't think the tank minds it though as I have great growth and color. I don't need the heater as I have 720watts on my 55gal(2X250watt MH, 2X110VHO). It doesn't usually vary that much unless the room temp is up. When it gets warmer I use the AC to cool the house and it stays at 80ish. We have had a warm spell the last two days so the tank is near 84. Any higher and the AC gets turned on or the window gets opened. Anything above that and the SPS will bite the dust.
02/17/2006, 01:27 AM
Oh yea, I wish I could afford Tunzes! That would help alot! Too many Maxijets, electric kills man.
02/17/2006, 09:26 AM
I remebered that I read this article as I was making up my mind on parameters.
Metabolism was also a factor I considered. It's an old freshwater habit as well to keep the temp on the lower end unless a species specifically requires it, also because of the bacteria and parasite factors.
It occurs to me while reading this thread, however, that since so much of our filtration process depends on the activity of bacteria, does one factor offset the other for no gain. What I mean is if we slow the metabolism of the fish and corals reducing feeding and waste production, is that offset by less activity on the part of the bacteria that is breaking down the lower waste load?

80 - 81 F

For those trying to keep their temperatures up, styrofoam around the non viewing areas helps keep the heat in. Michael R
