Exposed corals during water changes
During water changes, leaving our corals exposed to the air for a brief time isn't that big of a deal. However, since it's winter and the air temps are cooler, should that be a concern or not? My water temp is at 77 but my house temp is more like 72. Is that too much of a change in temperature for the 5 to 10 minutes the corals are exposed to the cooler air?
