The filters thawed at last.  (Although, which you will see shortly, not without a minor mishap.)  I was able to back wash them and add fresh water to the pond.  The Koi are happy and it was warm enough to have three bullfrogs hanging out in the water this evening.  I do wish this weather would continue, but it’s January and it’ll never happen.

     Early this morning DH managed to catch that I’d left the filter on rinse yesterday instead of remembering to put it back on filter.  (Things like this happen when I try to multitask too much.)  Yesterday the still frozen filters weren’t even trickling so there was no water loss until today when they began to thaw.  Fortunately, DH caught my mistake before the water level went down more than an inch.  However, scrambling to correct that and get the hose in the pond to add water exhausted him.

     The filters are functioning.  The waterfall is falling.  The fountains are working…all is right in the garden.  We’ll wait for spring to find the leaks in the waterfall.  For now all we can do is try to keep everything operating as best as we can.
