+1 with what Bob Lusk said.

I run the diffuser in mine during the winter (no kids). After both of my dogs almost drowned in the pond (couldn't get back up on the ice in below zero weather) I moved my diffuser so that it keeps an ice free hole to the shore.

Even so, with winter aeration it's not recommended to go on the ice anywhere in the pond.
