article: Pond Maintenance
Plants and fish are going to depend on your maintenance of the water garden. If
you were to build a water garden and never perform any type of maintenance, your
fish, and plants will not be healthy and thrive, as you would expect. Of course,
some plants are going to be very hardy and they will take over the pond. Those
that are fast spreading will choke most other plants out. The fish are going to
try to survive in the water that is murky and contaminated.
The water becomes polluted with disease and brings death of the fish and plants.
A balanced environment in the water garden is what you have to achieve.
Maintenance of the water garden is only a few hours a month, less than what you
spend in weeding and maintaining many of your other gardens.
The balanced environment in the water garden needs less maintenance than a water
garden that is not. The plants in the water garden act as natural filters for
the waste from the fish. Too little plants and the environment are not balanced.
Too many plants and the water are not balanced. Too many fish in the water

the water garden control the amount of ammonia and nitrates that are in the
One thing about the fish in the water garden is some types of fish do like to
eat or dig at the plants that are in the water garden. If you are raising fish
that continually are digging at or eating the plants in the water garden, you
can put some type of under water barrier so that the fish cannot reach the
plants. The water should still be able to move through this barrier, but the
If you are unable to put some type of barrier between the fish and the plants,
you will need to install some type of filtration system. Not all water gardens
will need a filtration system if it is balanced between the fish and the plants.
Raising Koi fish, they often are known to dig at the plants in the water garden.
If you are on a strict budget, Goldfish might be the better choice for your
water garden so that you arenít faced with additional problems of the Koi
digging at plants so that the water garden is balanced.
