It seems that pond heaters, when used hard in very cold weather, have a two-year lifespan.  I have to replace ours this winter.  It isn’t heating well.  Without a heater in the pond, our lovely Koi won’t last through the winter.  I was glad to find them on Amazon and ordered two so I had a spare just in case.

     So far, we’ve been lucky with the old heater managing to limp along.  The pond hasn’t frozen over completely yet.  Sunday we’re supposed to have a day in the fifties with rain.  However, the temperatures will take another dive after that.  I hope the old heater survives until the new ones arrive.

     I also hope the Koi stay healthy in the meantime.
