Hello, I would not do anything! Remember!! We are trying to DUPLICATE what nature does, that is give our koi a replica of what nature has mastered! So in nature when the water freezes , there are no changes of water! If anything throw a plastic ball into the pond, this will help that it does not freeze over, this will not change the temp.
