Koi Treatment Options and Solutions

posted in: Aquarium & Fish | 0

A koi pond is a beautiful and ornate addition to any backyard, but like any pet, koi fish can easily become ill. Though the fish are naturally hardy and can survive for weeks or even months with a minimum of food, certain contaminants in the pond can cause sluggishness, sickness, and death. Prepare the pond ahead of time to minimize potential harm to your fish. Any pet store or aquarium supply company can provide most of the materials necessary to treat your water or the koi if they become ill.

The pH level of your pond is one of the most crucial elements to maintaining a healthy stock. Koi fish thrive in still lakes and ponds rather than faster streams or rivers, meaning that the water often stagnates and the pH levels rise accordingly. While a pH level of seven to eight is acceptable for any fish — water from hoses or taps is around seven point five — purchase an acidity tester to make sure that it does not fall below seven. In low acid water, koi find it difficult to move and breath. If chalk like rocks are in the pond, remove them to prevent drops in pH level.

Sick koi are a result of bacteria in the water or a particular parasite. In the case of either, the fish will swim slowly or not at all, and may brush up against rocks or plants to relieve itching or soreness. Isolate sick fish and change the water immediately. Anti bacterial and parasite treatment medicine is available at any pet store; apply it to sick fish and ensure that they are entirely symptom free for at least three days before returning them to the main pond. Small growths of white or splotches of unnatural color should be eliminated in under a week with proper medicine treatments.

Certain ponds have poor oxygen circulation as a result of overcrowding. No pool should have more than one fish per five cubic feet. Use an air filter to revitalize a koi pond with a shortage of proper oxygen. Koi that frequently come to the surface to gulp air are a symptom of low oxygen pools.
