I use a Luft Pump with a double exit air line to supply air to the bottom of
my 2 adjoining ponds. I leave the pump on my porch, as I know that they
should not be exposed to the elements. I let this run 24/7-----365 days a
year. In the Winter, I move the tubing closer to the top of the water so as
to not disturb the bottom water, but to keep a hole open in the ice.

I'm thinking with this extreme heat this Summer, that I should be supplying
more air. What is suggested for a 1650 gal. pond?

THANKS----
