Covering Pond for Winter

I must have an old catalog - no heaters on p. 361. Do you know the
brand? I am seeing a lot of glass aquarium type heaters which I would
think wouldn't be safe in a pond. With the metal heaters, how do you
keep it from burning the liner?

p. 361 of aquatic ecosystems catalog, $44 and extra 30 for the controller. but they
got titanium that are cheaper. mine has a separate temperature probe and the heater
is covered to prevent it from getting hit or melting liner down. people in warmer
zones dont understand that our ponds drop below 50o (when koi's immune system goes
down and feeding stops) sometime mid october in zone 5 and doesnt rise over 50o until
mid april. that is 6 months of no immunity and 6 months of no food. it is VERY VERY
hard on koi. you can always order some kind of pool from aquatic ecosystem, or,
build a stud wall pond in the basement and line that with permalon. Ingrid

What kind of heater are you using? I've heard of people using trough
heaters and there seems to be several kinds of pond heaters. I only
have 500 gallons in Chicago.

It is early, but my first year I lost all my Koi (used a bubbler to
keep hole open). Last winter, I brought them inside. They are now kind
of big to bring inside. I am trying to plan ahead. If I need to bring
them inside this winter, I need to buy a kiddie pool and you can't
find them in the winter in Chicago.


I do not know your situation but I am in New Hampshire. Last winter
was one of the worst on record for low temps and high winds. My pond
is 40" deep. I kept a bubbler going (had to break ice open a few
times) and that was it. We started the winter with 1 koi, 3 goldfish
and 8 goldfish fry. We lost only 2 of the fry.
