ALL of the WH in my VF came from my neighbors pond. He sunk some WH to the
bottom, which is around 3 feet. I am in Zone 6.

I have never heard of that being done.....maybe I will try it....problem is
goldfish pond is 18 inches...to put them 3 feet down I woud have to put them in
with the BIG koi who would probably eat them over the winter....might try it
however. Jerri
