What would be the lowest water temperature survivable by either Koi or Goldfish?
Gill,
Jim and I circulate our pond water all winter here in Jackson. The
pump pulls from the bottom of the pond (deep well at 7'). That means
that the whole pond goes to 32 degrees when we have ice on the
top...which we have had for as long as several days. The koi and
goldfish did fine.
