9 Tips to Improve Water Quality in Fish Pond

How to Improve Pond Water Quality in Fish Ponds

Let’s first discuss how to improve the quality of fish pond water. The quality of the fish pond water directly impacts the growth and health, and can be a factor in the development and survival of fish. Poor water quality can lead to large numbers of fish death and economic loss for fish farmers. Any parameter that affects the water quality directly impacts fish health.

High levels of ammonia, dissolved oxygen, and nitrite in the water can lead to stress and diseases in shrimp and fish. In the variable and complex environment of fish ponds, water quality parameters can also interact. Temperature and pH imbalances can lead to increased toxicity for ammonia or hydrogen sulfide. For both growth and health of fish, it is important to maintain a balanced water quality. How can you improve the water quality of fish ponds? It is possible to improve the water quality of fish ponds and increase the survival rate for fry.

How to Improve Fish Pond Water Quality

1. Enhance Water Injection and Change

Regular water changes are a good way to ensure water quality in fish ponds. Anaerobic fermentation creates ammonia, nitrogen and hydrogen sulfide, which can deteriorate the quality of the breeding water. This is especially true during high temperatures. You can reduce the frequency of water changes if the fish pond is unable to maintain its water quality. However, this should only be done every three to four days.

Fish will react to stress if the water is not changed regularly. It is important to regularly add water and change the water in the fish pond. Water should be added to the fish pond every 7-10 days, at a depth between 20-30 cm and 30 cm. In summer heat, it is important to keep the water level as high as you can.

2. Reduce Fish Density

If there are more fish kept or the pond is small, the culture density will increase and water quality will be difficult to maintain. The best way to improve the quality of fish pond water is to decrease the culture density. If your pond holds more than 10 inches of fish per 100 galallons of water, it is likely that you have too many fish. Excessive numbers of fish can lead to excessive fish waste and a pond with too many fish can cause a pond water imbalance.

3. Don’t Overfeed Fish

Too much dirt in the water is the main reason for water quality decline. Overfeeding can cause this dirt to be made up of fish feces and leftover bait. The pond rots if you give your fish more food than they can consume. You should not feed your fish more often than once a day, or for longer periods than they can consume in a matter of minutes. To improve the quality of your fish pond’s water, you should choose high-quality fish foods. The fish will not finish the fish food and the food will sink to the bottom of the fish tank, causing water pollution.

4. Proper Oxygenation

Proper oxygenation is essential to improving fish pond water quality. It depends on the weather, fish activity, and the opening time of oxygenation equipment.

It should be switched on every day during peak fish-growing season to increase the oxygen level and create a healthy environment for the fish. Emergency measures can be taken to boost oxygen levels by spraying chemical oxygenating powders.

5. Before they Rot, Get rid of all contaminants from ponds

Leafs and twigs, as well as fish waste, can all fall to the bottom. If these contaminants aren’t cleaned up promptly, they can cause the pond to become contaminated and increase ammonia levels.

Ammonia can be harmful to fish and should be removed immediately. Ammonia levels may have reached a peak if your fish jump out of the water. An ammonia tester can be purchased to check for ammonia levels. If you find high levels of ammonia, an ammonia neutralizer can be used to improve the quality of your fish pond.

6. Restoring the Breeding Environment

Sprinkle live bacteria granules over the entire fish pond (main ingredients). Bacillus subtilis. Nitrifying bacteria. Denitrifying bacteria. Sulfur bacteria. Zeolite powder. Calcium, sodium humate. Oxidating substances. Once every 7-10 days. Transform ammonia nitrogen, nitrite, hydrogen sulfide, etc. In the pond, into sulfate and nitrate, and other substances used for phytoplankton. This will allow you to quickly restore the ecological breeding environment to improve the quality of the fish pond water.

7. Transparent Monitoring of Fish Pond Water Quality

Rich algae can be sprinkled over the entire pond if the transparency is too low (main components: probiotics and polysaccharides; organic matter, probiotics and polysaccharides; amino acids and nitrogen; calcium, magnesium, iron, and other elements); every 15 to 20 working days.

To improve the transparency, splash chlorine dioxide (main components chlorine dioxide, stabilizer and activator) into the entire pond. This will make the water more clear.

8. Use Reasonable Quicklime

Quicklime can be used in breeding ponds to purify water, regulate pH value and prevent fish diseases. It is recommended to be used every 15 days. The dosage is 10-15kg/mu. The pool can be sprayed with quicklime if the pH is too low. It is recommended to use the pool at 9:00 AM on a sunny day.

9. Use of biological agents

Regular use of photosynthetic bacteria (Bacillus, substrate enhancer), etc. In the breeding pond, the microbial decomposition and removal of toxic and harmful substances (ammonia nitrogen, Nitrite, etc.) is conducive to improving the quality of the fish pond water and increasing the fish’s immunity.
