Safe to use stored tank?

[earhtmother]

I have a tank which has been stored outside, under cover, in freezing temperatures for a couple of weeks. Do I have to worry about the sealant if I bring it in to use? It was fine before the temperture dropped but now I am not sure

Just don't go straight cold to warmer temperatures, that can stress the glass and could shatter it. Should be fine otherwise

I have 're activated 'many tanks after a winter in the attic over the garage...Sometimes during the winter. Just let the tank warm up for a couple hours before doing anything with it.
