pond heater

[Hustler]

I hear trout pond keepers use trough heaters the brass ones that are 110V to keep the surface clear of ice in one area..... must have giant arreration though.....
Ive seen koi survive a 6' deep pond with 2 big monster pumps running through the winter..... but i chaulk that up to luck.....

Thank you. I've been using heater and air pump for the last 2 years, but every year have to replace a new heater. That's why I asked for a reliable heater.

I ran a floating de-icer with a small pump circulating the warm water all winter long. Killer on the power bill but even in -35 degree temps I had open water.
