Pond Boss Forums STOCKING A NEW POND Types of fish to choose Cecil envy

Bruce (this may all be terribly obvious):

I'm assuming from the pictures that it's a newer building and is sealed pretty good.

I think as Winter goes along and the ground temp drops, the inside temperature will be lower and closer to what you expect. Inside temps in our horse barn (overnight, when all the doors are shut) tend to go down all Winter long. It's a lot like the bottom of a pond having a higher temp at the beginning of Winter due to the stored solar energy from Summertime, which slowly dissipates.
