Hmmmm ...i only have to run a line about 6 feet from the window in our
basement . it will ice up i'm sure, maybe heat tape could solve that prob
when needed ? This sound like all this could be a pain. We dont have any
fish ... the frogs loved them.

Hi Bill - There are 2 possible problems with locating the pump inside your
basement - condensation and distance - the air in your basement will be
warmer than the outside air and will probably cause condensation in the
airline to collect and freeze up (I put my airpump in a small rubbermaid
container and locate it on top of my 45 gal bio filter and run the line
( ~
15') at a constant down slope to the airstone 3" below the water surface
so
no condensation can accumulate - others here have had freeze ups from
loops
or low spots in the airline ) - The longer the distance you pump whether
air or water, the less you get at discharge, although you could compensate
for that with the size of the pump and line

hi,
im new here and have read quite a bit about ice on the pond and
wondered
if
an air pump located in our basement could force enough air thru a tube
to
keep our pond free of ice with a hole large enough to allow gasses to
escape? it gets pretty cold up here 0 to 20 below
