we just had a blackout the other day, especially in summer here in southern cali theres tons of them. **** wet/drys i like to fill my tanks a little higher than needed so i wont see the waterline behind the canopy but then if power goes out i get a little flooding action. get the battery backup air pump. most houses shouldn't get too cold during short poweroutages i just throw a heavy blanket over the tanks to be safe but most of my tanks are big so they take a while to cool down if theres little water movement.
