Temp change question

[Sexytang]

i had been keeping my tank at 80-81 today I changed my heater temp to around 76 before I left my tank was really warm and i had been told heat would cause corals to act funny. Well I come home from the store and several of my corals are closed up. Could it be due to the change and will adjust

You need to gradually bring the temp down over a period of days/weeks.

Try increasing slowly. 2 degrees max a day. Most people shoot for 78.

Have you checked the temperature with a thermometer? The heater temp gauge could just be off and that 76 may actually be 74 (which means that when you had it set at 80 it may have actually been a perfect 78).

80-81 shouldn’t cause issues. You can safely drop the temperature where you want it. If you don’t have a temp controller you are playing with fire - sooner or later your heater’s thermometer will fail.
