tank freeze

[shsulax]

Hello all,

I have just been introduced to the hobby and am loving it. Ive had many freshwater tanks in the past but am just know getting my feet wet with saltwater and i have recently had a little problem.

here is everything about my tank that i know:
12 gallon nanocube
20 pounds live rock
1 green seabae anemone
1 tounge coral
bumpy mushroom rock
1 large feather duster
1 small galaxea coral
1 cluster of some type of polyp
1 percula clown
pH 8.2
salinity 1.025
Temp before 82 F

It froze the other night where i live and i wasnt at my house to check on my tanks. All was fine before the freeze with water temp around 82 F but when i got back i noticed all my corals looking pretty bad. when i had a chance to check the water temp i found it was 60 F. i Immediatley put a heater from one of my fresh water tanks and got the temp back up. today i checked every thing again and they all look better just not as healthy. Some of the polyps look pretty rough (maybe dead?) and the feather duster wont come out-will they get back to normal or am i going to be investing in some more livestock? How do drastic temp changes effect the corals? ph and everything else has remained the same.

thanks

It is very possible you will have some die off. Keep an eye on everything and if you see anything polluting the water you will probably want to pull it quickly. It won't take much to bring down a Nanocube with about 8 gals of real water volume.
