Add life to your pond - add fish
 Fish
add life and movement. Not only beautiful and graceful, fish also serve
an important function in the ecological balance of a pond. They feed on
unwanted visitors, such as mosquitoes and chrysalis, and excrete vital
nitrogen for pond plants.
To keep fish in your pond, you´ll need to provide the right conditions.
Your pool´s size, shape and plants life are just as important as
the right technology. Each help to ensure the provision of oxygen and
aids in maintaining a constant current.
The best time to add fish depends on the age of the pond and the water.
In any case, you should wait until the ecological balance in the water
has established itself (3-4 weeks minimum).
The right amount of fish for your pond can be roughly determined with
the following general rule:
General
rule: |
Up
to 2 Ibs. of fish per 256 gallons of water and a minimum recommended
depth of 3´. |
 There
are a number of different fish varieties available in shops: Golden Orfes,
Shubumkins, Tench or Sarassa Comets are just as suitable for your pond
as Goldfish and Koi.
Make sure that you buy these fish from an aquatic retail specialist. Fish
from wild ponds often carry parasites and germs which could infect the
fish in your pond.
A very special pond is the Koi pond. Its size, depth, plants and technology
differs from other fish ponds. A Koi fish pond generally needs to be at
least 3´deep. When the fish stock levels grow, the filter technology needs
to be powerful and easily expandable.
The filter capacity has to be calculated exactly for the existing fish
stock levels and water quantity to offer the fish a perfect living environment.
Plants for a Koi pond need to be chosen carefully since Koi love to eat
pond plants. Therefore, it is advisable to avoid sensitive little plants
and choose robust plants like water cress instead. Apart from eating plants,
Koi also like to wallow in the mud at the bottom of the pond. To avoid
this, it is a good idea to cover the bottom with pebbles.
Koi need company. They grow quite old and will continue to grow in size.
Consider the important fact at right when constructing a Koi pond.
