4 Parameters of Healthy Fishpond Water

Cool Garden Design with FishpondTo get a healthy fishpond, you have to maintain the condition of the water in a good and healthy condition. Healthy pond water conditions will make the fish not get sick.

There are at least four water quality parameters that need to be taken to ensure that your pool is always in a good health condition. Those four parameters include water temperature, acidity and basicity, oxygen content, and salt content

The water temperature
The water temperature can affect the growth of aquatic vegetation and oxygen demand in the pond. The increase of water temperatures will lead to reduced oxygen. In addition, plants and fish will need more oxygen because the respiratory rate increases.

Basically, some fish do not have a problem with the  water  temperature. Generally, strong fish face temperature changes. Only, if the fish is imported from abroad, it must adapt to the water in our environment.

Changes in water temperature can result in changes in fish behavior. The colder the water, then the appetite and growth actually become more slowly. During this time, the portion of food should be reduced since if not eaten, the food will rot and make the water contaminated.

Acidity and bacisity
Acidity or bacisity of water is measured by pH meter. Acidity is one of the important factors that affect the water quality of fish health.

The level of acidity is measured by the quantity of hydrogen and hydroxyl in the water. The measurement scale is from 1 up to14. When the hydrogen ion is too much then the pH is too acidic. Whereas, if the hydroxyl is higher, the water is too bacicid.

Water fishponds generally require acidity from 6.9 to 8. This figure is close to the normal value of the degree of acidity. There are many possible reasons why the pH value below or above the normal value. Like many of carbonic acid metabolic waste of fish, it triggered the filter is not working well, and the pool water is not regularly replaced.

Fish pond water generally requires acidity from 6.9 to 8. This number is close to the normal value of the level of acidity. There are many possible reasons why the pH value below or above the normal value, such as the big amount of carbonic acid which is the waste of fish metabolism.  It is caused by filter which is not working well and the pool water which is not regularly changed.

Oxygen content
Oxygen content in the water should be sufficient. For koi fishponds, for example, the oxygen needed is about 6 milligrams per liter. The decrease of oxygen levels can be caused by the death of fish.

The oxygen content is related to the water temperature sot that if there is an increase on water temperature, the oxygen level decreases, and vice versa. The fall in oxygen levels could be due to the amount of water plants which are not balanced.

A big number of fish in the pond and a bad water circulation when passing through the filter also contribute to the reduction of oxygen.  To keep the oxygen level stabled, make a good aeration system.

Salt content
Although the fishpond contains freshwater, it is okay to make it contain salt. The salt functions to neutralize the ammonia and nitrate.

Ammonia is a waste produced by fish decomposition. In certain levels it can harm the fish. Allowable salt content is 0.15 to 0.20 percent. Too high salt content can damage aquatic plants, also interfere with the zeolite stone work on the filter. To measure the levels of salt, you can use a salinity meter, which costs about 70-80 dollars.
