Today's Pond Q&A

Today's Pond Q&A

In this issue:




I live in New Hampshire and have an 1100 gal 8' x 10' oval KOI
pond varing in depth from 16" to 30". Over the winter, I bring
my fish in. We have a walk-out basement, and I set up a 300 gal
rubbermaid stock tank in one corner with windows.

I keep a filter w/UV lite on full time. The water temp drops to
45 F and the fish do fine. I did have a few fingerlings that I
missed in clearing the pond late last Fall, and they survived
the winter outside. the inside tank will need to be covered with
a net or lattice work to keep the fish from jumping out (lesson
learned the hard way).

Thanks for sharing that with us, David. Yes, the choice to
bring fish in or leave them out is an individual choice, but
there is no choice as to covering the tank. Koi will jump.
Sorry you had to learn the hard way.

There are other variables that determine a fish's capacity to
remain outside- depth of the pond is just one. The surrounding
area and some sort of buffer from the wind is a great help to
many ponds. Those in open spaces do not do as well as those
enclosed in some way by either buildings, rocks or close
trees/woods on the north side.

When your fish become too large to transport to the basement,
you may wish to think about constructing either a larger, deeper
pond, a protective shelter, or heating the pond.

PS- the smaller fish seem to jump farther and quicker than the
big, fat old ladies and gents of around 30-35".

Dear Carolyn:

Your answer was music to my ears, and something I have been
considering for several years, but since my pond was an
aquascape designer I was very reluctant to do what you have
advised. Your entire explanation makes an enormous amount of
sense. I spend hours just keeping the pond clean.

One additional question if you got time. I have numerous water
plants in my pond. How do I anchor these plants so the Koi
don't knock them over, or the pond soil in the pots don't come
out of the pots? I now have them anchored with rocks, but of
course dirt and algae grow on these rocks. but not real bad.
I try to keep at least 60% of my pond in plants, and that appears
to keep the pond pretty clean and clear.

Thank you for your advice and your time. I will continue to buy
my products from Macarthur supplies.

Thanks for the feedback. In an Aquascape system, there is place
for floating plants in the waterfall which can take care of the
nitrate load. But these ponds were made to look natural and
that can't happen without plants.

My suggestion is to put your plants in the floating island
planters and Pond'Toons that use hydroponics rather than dirt to
support the root systems. MicrobeLift makes a planting medium
that is soil less also and would not contribute to the dirt in
the pond.

Koi will be koi and they will upturn plants that are not
protected either by a fence or securely fastened. They will
reach up out of the water to eat the plants and this will topple
over the best prepared pots. My suggestion is not to use soil
in any pots that go into a koi pond.

Any of the soil less mixture that lands on the bottom can be
vacuumed up without polluting the water.

- Carolyn


Happy Pondkeeping!
