Chiller emergency

[DTz]

Hey guys. My chiller went crazy and brought to temp from normal range of 25-26c to 21c lowest. I’m not sure how long was it like this for. Mebbe 1-2 hours. So far fishes all alive and swimming. Sps looks aleight just less pe. May I know what can I do or what to expect after such a drastic fall in temp?

I wouldn't expect to see any change as long as the tank is healthy.
