We have 3 larger Cois that we have brought
home from our cottage in Northern Michigan. It is our second
year keeping them in an Auquarium in our home over the winter,
they cause a terrible odor in our home. I have a few questions;
Could we leave our fish in our
small pond (4 x 4) (2 ft deep) It sometimes get below 0, and
we have no way of heating the pond because of electricity
being off in the winter months?
Ot if we take them home to our aquarium,
how do we prevent the terrible
odor that the fish cause in the house. What type of filter
should I be using?...We are just using the one that came with
the Aquarium, the water is dirty every other day, and my husband
seems to be clening the tank twice a week.
Please help.
Hi, Rose.
Your koi are too big, and ANY
aquarium is too small. Koi are very wasteful fish, and their
ammonia output will easily overwhelm any aquarium filter
on the market. The smell is, simply, too much fish and not
enough water or filter.
To safely overwinter
your fish indoors, you'll need a 250 gallon horse trough
from Farm and Fleet and your filter from the pond in Michigan
with the active
filter media still in it. You'll also need a pump capable
of exchanging the water at a rate that puts the full volume
of the vat through the filter once an hour. You'll need
a high-capacity air pump and a large air stone. Feed very
sparingly, especially at first. Your filter will need time
to restart following transport. Do not let the media get
dry during transport!
Leaving the fish
in the small pond you describe would be a bad idea. At that
depth and with those temperatures, the pond will freeze
over and any fish
in it will die of combined hypoxia and trapped organic gases.
