Question #1>

Hello Carolyn,

This the first winter that I am having koi in my pond and I would
like to know if i am supposed to turn off the filter. I have been
told to turn off my little waterfall and the my little water
feature so it does not pull the cold water down to the bottom of my
pond where my fish will be hibernating.



Answer #1>


That information is correct. Use a de-icer to keep the water at a
more suitable temperature. What other dangers there are in leaving
a waterfall going would be in that the water can freeze and the
pipes will burst. That can be costly and inconvenient come spring.

Question #2>

Hi Carolyn,

I started two years ago with a small 200 Gallon Pond with a
waterfall. My 3 Koi have grown from 6-8" to about 18" and several
pounds each. They have survived in the pond by having a Bio Filter
that is for a 1500 gallon pond.

With winter coming, I am considering releasing them into a nearby
large natural pond. Will they survive?


Answer #2>


Not only would they survive, they would threaten native species and
endanger the balance of nature in your area! I can't stress this
too strongly that non-native species, such as koi, should never,
never be released into natural waters.

The now notorious kudzu vine that is eating up the south,
overtaking everything in its path, is a good example of an alien
import and what it can do to the environment.

In Maine, koi are outlawed, to own or to sell. Maine is taking
necessary steps to protect their native environs. If we are not
responsible with our fish, we will face the same legal
interventions not too far down the road.

Do not release these fish. If you cannot find a suitable home for
them, you have to humanely euthanize them. I'm sure if you
advertised properly, somebody would take them off your hands.

Question #3>

Hi Carolyn,

I read your article about keeping herons out of ponds with much
interest. However my problem is not herons - at least not yet!

My problem is water snakes. We live by an irrigation ditch from
whence the snakes like to migrate to my pond in order to feast upon
my fish. One came out of the pond one time with a wiggling fish in
its maw which it proceeded to lay at my feet since the fish was too
big to eat.

I must have killed ten or eleven snakes this summer, having given
up trying to toss them back into the ditch to no avail. They always
came back for a visit. Any suggestions on how to keep water snakes
out of my pond?


Answer #3>


You must have a den nearby. Snakes live in dens, like bees in
hives. I just received another question like this and my answer is
the same: remove any grasses, rocks and plants from around your
pond. The more open it is, the less cover the snakes will have.

Remember, even snakes have enemies and would prefer to stay under
cover. Hawks and eagles would relish a snake for lunch. Is this
why we first began mowing our lawns, to prevent unwanted guests in
the grass?

You can also put netting around the pond, secured in the ground
around the pond, to a height of about 2-3' which may keep them out
of the water. Like any predator, if you make it difficult enough,
they will go elsewhere. Is there any other way of making a wall or
barrier between you and the irrigation ditch?

Oh, and remember, never try to shoot a snake by your pond. The
bullet will make a big leak in the liner and you will probably miss
the snake.

Question #4>

Hi Carolyn,

My question is about adding water when do a water change. If I hose
tap water directly to the pond and add chlorine neutralizer at the
same time will it work? Or do I have to neutralize the water first
before I put it in the pond? If this is the case is hard to find a
big spare container.

Do you have a way to neutralize chlorine first before you add that
water to the pond ( 3000Gal and 15% water change).


Answer #4>

I actually add dechlorinator as the water is refilling, directly to
the pond. I just need to know how much water I am putting in so I
can measure the right amount of dechlor. Ideally, the container of
dechlorinated water is the best solution, but not necessarily the
