I have been storing fuel in my full scale hangar for years, both mixed and unmixed Kero......I actually use a 1-K kero that is jugged up in Canada by RECOCHEM, INC......today it is a steamy -7C for the high, with a Canadian Blue Norther' blowing over the state....

Zero problems.....always crystal clear in the spring......stored on the concrete floor....temps in January get down into the low teens in the hangar......algae definitely won't grow.....too cold, and it grows in liquid water at the kero interface, not the kero....... any water at that temp is martini ice......
