In the future it would be a good idea to have an air pump and air stones to
prevent the depletion of the oxygen. It is also a good idea to have some
hydrogen peroxide available. A dose of about a pint per 1000 gallons will
kick the O2 level up and save the fish and make the work of oxygenating the
water much easier.

Hi , I have had my pond about 7 years. I am in upstate NY with frigid
winters. Yesterday I had a major crisis. When I woke up the waterfall was
not working. I went out to look and noticed the pond had gone down about 8
inches (12X15---2200 gallons)
The Koi were in major distress, especially my largest blue one. He is
about
2 feet long and was upside down f(. I assessed that there wasn't enough
oxygen in the water and proceeded to take the steps to correct it. I
worked
furiously all day. About 2 in the afternoon everyone seemed to be
stabilized
. I thought I saw MR Blue swimming but I have not seen him since. I am
hoping and praying that he is still alive but if he were not would he
float
to the top? How long would that take? Thank you for any help. Sofia of
the
Pond
