What Temperature Do You Keep Your Tank

[videosilva]

1. I am curious at what temperature everyone keeps their tanks at ?

2. I am interested to know the effects of different temperature on the coral ?

3. Has anyone experimented with different temperatures and noticed any substantial response.

4. Why do you keep your temperature at ????

Between 78-82,, other wise it's an extreme coral mutalation!!!!!

I myself keep my tank between 78 in the winter and 80 to 81 in the summer. I like to give a seasonal variance in temp. I would not go higher then 83 for long term as this can cause bleaching and color issues. Higher temp or lower temp also speed up or slow algae cycles, disease gestation periods and food web production.

Higher temperature within proper range do speed up metabolic rates so things like calcification rates increase. To high a temperature does cause heat and light stress for the corals and significantly lowers light saturation levels that they are able to take throughout the day. Making less usable hours for food production during photosynthesis and less light the coral can handle if the coral had been in optimal temperature range.

What that means is to high a temp and the coral hits its light saturation level earlier then it normally would have if it had been at lower temperatures. Because of the overproduction of the Zooxanthellae, the release of CO2, build up of byproducts from photosynthesis, it slows and can even stops calcification rates till the coral can deal with the buildup. The coral needs to respire out and process the built up of byproducts before it can return to normal growth and calcification rates.

I do find lower temp like 76-77 slows growth of corals and the 78 to 81 range seems to be best for calcification and coral growth in my experience.

^^^ And there you have it.right from Kman^^^
I myself aim for 79°- 80° and Never let it fall below 78°.
Although I dont do the seasonal drop. Living in an older home right by the lake sometimes it happens "naturally. Lol

78-80

75-76 no coral issues or growth issues

Touche!!
Have tank set at 78. As expected, fluctuates .5 degree either way.
Alarm set to go off if more then a degree. Doesn't seem to go off very often. Sometimes with a larger water change.

Keep mine at 80, read a report that stated below 77 calcification slows drastically something like 50% and when they kept the temp. below 77 for long duration the coral would die.

English Guys this is Canada We use Celsius and Centimeters/Millimeters, NOT Fahrenheit and Inches

My tank is at a Steady 25 Degrees CELSIUS

Well I guess my age is showing, when I was in school was when they switched and what a mess that was, they tell everyone that what you have learned to that day forget it, Ya right. It was not easy and still is hard for me, Auto class dealt with Standard or Imperial because of the Auto industry and Woodworking or Carpentry to this Day use Imperial measurements, so for you when you try and figure out what 3/4" is I am trying to figure out what 19mm is. So sorry if I caused any confusion I keep my tank at a steady 26.6667 Degrees CELSIUS.

corals will not die if tank is below 77 my take was at 75 for over a year heavy sps nothing was dying or growing any slower than when I have it at 77.5 now ! The ocean is rarely 80 so unless we know more than Mother Nature this is not true I was just in Florida last week and that water is friken cold lol

you must be an office guy were construction guys lol metric is useless other than machining.

I keep my tank at 78 degrees for 8 months and 80-81 for 4 months.... managed to get my coral to spawn so they must like it

Thats why coral in the wild grows so slow. The lower the temp the lower the metabolism the slower the growth. My 4 months of 80-81 i get almost twice as much growth compared to the 8 other months at 78

Florida in Feb. and that is what are comparing reef temps to. It also can snow in Florida. Most SPS that we get come from Indo Pacific and now some from Australia where water temps Avg. are 26 to 30 Celsius or 78.8 and 86 F and 27 Celsius 80.6 being the majority of the area. Now if you were able to keep a thriving SPS reef tank at 75 all the time I consider you to be quite lucky. I sure some have read this before but if not is a good read.
