View Full Version : Minimum Temperature

07/19/2009, 07:55 PM
I am in the process of setting up a system that will house fish that require cooler water temps. I plan on maintaining the water temperature at 70-72 degrees year round. Is this too low for SPS corals?

I would think that temp is too low for sps. Most people keep them at 78-79. Maybe others will reply.

I agree, that seems too low for sps. Ideal temperatures are more around 79ish.

FWIW there are other types of polyps that you can keep in your aquarium, however the sps you find in this forum are not among them. Most will looks more like a single poylp, or a group of polyps; also soft soft corals. Steve weast had a very nice coldwater tank that was shown years ago on RC you might be able to dig up the thread with a little work. Good luck. There's some very cool coldwater species out there.

Thanks for the replies.

Is there anyone else with any ideas on this?

I let my tank get down to 74-75 at its coldest, but since I am in so fla it doesnt get their often, maybe in the evening. Its typically around77-78 degrees. 72 might be pushing it, but 75 will work well for sps. By the way heating a tank is easier than chilling. Why do you want to maintain 72? Where did you get this magical number?

There is a fish that I will be adding to this tank that NEEDS cooler water. I will be adding a juvenile, and these little guys are collected very deep and do best at temps in the mid-high 60s and low 70s.

Is the cold blood fish reef safe?
