Safe Temp Fluctuations for Acropora

i've been logging my temperature every few hours for the past few days. there is definitely some temp variation. what is a safe range of fluctuation for acropora to remain healthy?

I get about a 2 degree variance throughout the day and my Acropora are fine and growing like weeds

I start with the tank at 77 first thing in the morning, and by the time my halides are off in the evening, I'm sitting at 80-81. Been like that for the last yrs, still looking good.

IMO its not the swing, its how slowly the temperature raises and cools during the day. A very fast swing doesn't allow the corals to acclimate gradually to changes while a slower swing, they almost don't know its happening. I did have my tank swing from about 78 to 92 a few days a couple of summers ago (pre chiller) without any side affects. However this does not mean that your tank is safe or you won't experience a problem. A swing of 3-4 degrees seems to be normal for most tanks.

I'm assuming you mean wild colonies and cultured? I have both types in my tank
