This page
has information about fish ponds
and good fish for ponds. You can
read about starting a pond, about
picking a good place for a pond,
about choosing good fish for ponds,
and about caring for fish in ponds.


1. What Kind of Pond?

There are many choices. The pond can be made
of plastic, or half of an old wooden barrel
with a plastic liner, or a concrete pond with
or without an epoxy or tile coating.

Some pond
keepers put dirt in the bottom of their plastic
or concrete ponds to make their ponds more organic.

Ponds also vary greatly in size from a few gallons
to many thousands of gallons.

Lets suppose that you have a plastic pond holding
40 or 50-gallons of water, or maybe half a wooden
barrel with a plastic liner like the one shown

Ponds like this can be bought in the
spring from local stores that sell pond supplies
and from online stores.

2. How to Start a Pond

Your pond probably comes with some instructions
about how to install it. Carefully read and
follow those instructions.

The instructions
may recommend that you add a

water conditioner
to neutralize some of
the chemicals that your local water department
adds to the tap water.

Don’t be impatient. Fill
the pond with tap water from the faucet, add
some water conditioner, and wait at least three
days before adding any fish.

You’ll also need some floating goldfish food,
which is appropriate size for your fish. Get
an 8-inch fish net with a handle long enough
to reach everywhere in your pond.



3. A Good Place for Your Pond

You can put your pond almost anywhere, but not
where a lot of leaves or other debris will fall
into it.

Or you could cover your pond with lath
or screen probably available at Home Depot.


Ponds use quite a bit of water, so it’s convenient
to put your pond near the plants in your yard
and pump the old water from your pond on to
those plants.



4. Good Fish for Your Pond

We recommend one of three choices


Fantails and Orandas


Pond Comets


Koi and Butterfly Koi


Fantails and Orandas are less aggressive than
Pond Comets and Koi. If you prefer Fantails,
do not mix them with Pond Comets or Koi.

can mix the Pond Comets with Koi, but a good
many Koi keepers decline to do so because their
Koi are often worth much more than Pond Comets.

We’ve never felt that way, but then we’ve never
owned a $10,000 Kohaku Koi.

5. Change Water in Your Pond.

Change 20% of the water in your pond twice each
week. Remove some old water from your pond and
replace it with fresh tap water from the faucet.

In most areas of the country you don’t need
to add conditioner to the water when you change
20% or less. But changing more than 20% can
be risky even when you add conditioner.


to see my 8-year old nephew, Nicholas,
helping me clean the gravel and change some
water in my pond.

How much is 20%?


for information about measuring and
calculating volumes.

In my barrel pond, shown
in the photo at the top of this page, the sides
are almost vertical. so 20% of the volume of
the water in my pond is 20% of the depth of
the water in my pond.

This method won’t work
unless the side are nearly vertical.

I measured the water in my pond at 13″ deep,
and 20% of 13″ is 0.20 x 13″ = 2.6″. So I remove
2.5″ of water twice a week.

The water coming out of a pond is better for
plants than the water going into a pond.

your pond won’t really use much water; it will
just borrow the water for a while, before it
goes on your plants.

If you have a pond that is below ground level,
you should get a water pump and use it to remove
the water from your pond.

The inlet to your
pump should have a screen, so it won’t suck
up the fish. After you’ve removed 20% of the
water, refill your pond with tap water.
