Corals and lower water temps....

Can our corals survive in lower water temps?

I thought about this due to a wedding I am going to in Fort Lauderdale in December. I figured while I'm there, I might as well drive down to Key Largo for some diving on the reefs. While researching water conditions in Key Largo for December I found that the water temps are usually in the low 70's. I know Key Largo is home to both LPS and SPS, along with ric's and other stuff....so if they can all survive in the wild in the low 70's why can't they survive in our tanks at the same temp?

Can they survive in low 70's instead of 78-80?

Corals can survive at lower temps year round, not all can are as hardy. Wideband clownfish are found in waters no higher then 77 and no less then 70. Anemones live in these temps and so do corals in that area.

I keep my tank at between 74- 76 and have no ill affect. I also dont keep sps.

Most corals can are okay in the 75 =80 range, temps below can cause some sps to stress but zoos and lps and anemones can handle it.

I also kept my tank between 74 - 76 and had no ill affects for many years. I was speaking with Dr. Mac a long time ago and he said the collectors he was dealing with told him the water temps were a constant 76 degrees. So that's why I targeted those temps.

Barry is correct.
We typically try to keep our tanks at about 75 degrees, our SPS do fine in that range.
Don, in March of 2009, when we lost power (before the days of owning a generator), our tanks dipped down to 55 degrees. Most of the LPS and zoas survived, but we had serious losses of SPS. Deepwater acros did ok, but our acro losses were nearly 70%.

In our old apartment in Brielle, our 12g stayed at about 72 degrees, with no ill effect on the LPS or zoas that it housed.
I believe Stan (SM Cooler) runs his tanks cold, but I do not recall the exact temperature he keeps his tank at.
