Keeping pure from freezing

[Posh]

Anyone any idea how to stop it freezing. I keep mine stored in 3 water butts & last year wrapped bubble wrap round em which was pretty good but we had a pretty mild winter.

Racking me brains what to do this year.

Any ideas??

Pond heater dunked in the water butt.

Float some tennis balls in them?

isopropanol,aquarium heaters.i store my water butts under a lean to & when it gets really cold, I use a paraffin light which produces enough heat to stop freezing.it can be a fire risk if not secured correctly tbh.

Yeh I've got two aquarium heaters that I've squeezed into a piece of foam. So I just throw them into my tank so they float and heat the water
