Thanks for the interesting article

Hi,

Good information, thanks. I have my first in ground molded pond installed last fall, (September). It is 365 gallons with a15 gallon filter reservor plumbed into and next the pond where it works well and is out of site under a large shell type plastic rock. I was concerned about the pond freezing over with those cold snaps we get here in the northwest, (Tacoma).

A friend suggested using submersable aquarium heater. So I put a 150 watt aquarium heater in the reservor. It works great and it never let the water temp. drop below 40 degrees F, or above 50 degrees F. It did create big a problem with water evaporation. About every other day I had to add a 5 gallon bucket of water. So I drew only hot water into the bucket from the kitchen tap, and then I would add dechorinater to the hot water. Then I would set it aside indoors until I needed to add more water to the pond.

I have a friend Auburn, WA. that has a large pond about 1000 gollans in her back yard, and she uses a commercial pond heater during the winter months that she says works good.

Hope this works for someone else with the same concern about freezing.
