In order to maintain the health of your pond fish, it is essential to provide the appropriate sized pond for the number of fish you have. Care for pond fish by providing clean water and proper nutrition, this will assure that your pond fish will flourish.
Having an adequate sized pond for the number of fish you have is critical for the health of your fish. If the amount of fish is too large, you will have a decrease in the water oxygen level and increase in the amounts of ammonia and nitrites from the fish waste. You can have more fish in a smaller pond if you have a filter that can filter the water quickly and efficiently. A filter made for a larger pond can be used for a smaller pond to assure that the water will be properly filtered.
The most important factor in caring for pond fish is proper water quality. Inferior water quality can cause stress for the fish which can lead to illness. You want to make sure that you pond water is not getting contaminated by toxins from run off water or by chemicals that may be sprayed around the pond itself. It is recommended that you test your pond water once a month, weekly testing is ideal. Make sure that you test the water at the same time of day because pH levels can change. You want to test the water for ammonia, pH level, and nitrites. Ideally you want the ammonia and nitrite level in your pond to be zero. High levels of nitrites or ammonia can signify that you have too many fish or that your filter is not working adequately. The best pH range for your pond is between 7.0 to 7.8. An acceptable pH range is anywhere between 6.6 to 8.4. If a pH change is needed, it is best to do so gradually. A sudden pH change can harm your fish.
The next thing to consider when caring for pond fish is correct nutrition. Fish will overeat if allowed to so, it is important to feed the correct amount of food as well as the correct type of food. When feeding your pond fish, you only want to feed enough food that can be consumed in a few minutes. Food that is not eaten can contribute to dirtying the pond water. It is recommended to feed several small meals throughout the day as opposed to feeding one large meal.
