In shrimp farming, pH value not only affects the physiological activities of shrimp, but also directly relates to the growth of other microorganisms and algae in the water body. Too high a pH can lead to the death of beneficial microorganisms in the water body, which can affect the balance of the entire ecosystem. So, how to effectively reduce the pH value of shrimp ponds?
First, the introduction of acidic substances
Add an appropriate amount of acetic acid, lactic acid and other acidic substances to the shrimp pond to neutralize the alkaline substances in the water body and reduce the pH value. The breeding friends around me are more recognized: the water body is a pioneer, containing fruit acids, organic acids and detoxification factors, etc., which can quickly adjust the pH value, decompose algal toxins, and detoxify and regulate water.
2. Increase the frequency of water changes
By changing the water regularly, the high pH water can be replaced with a low pH water body, which can quickly reduce the pH value of the shrimp pond. However, it is important to note that the new water should be of good quality when changing the water to avoid introducing new sources of pollution.
3. Adjust the amount of feed feeding
Reducing the amount of feed can reduce the accumulation of organic matter in the shrimp pond, thereby reducing the alkaline matter produced during the decomposition process.
4. Biological regulators
Bioregulators, such as certain microbial agents, can indirectly reduce the pH by regulating the microbial community in shrimp ponds, promoting the decomposition of organic matter, and reducing the production of alkaline substances. This method is more environmentally friendly, but it takes some time to see results.
Fifth, increase aquatic plants
Planting some aquatic plants that can absorb nutrients in the water, such as duckweed and water hyacinth, can not only purify the water quality, but also reduce the pH increase caused by algae overbloom.
Sixth, prevention first
In addition to the above measures, we should also focus on prevention to avoid the occurrence of excessive pH value of shrimp ponds. For example, the rational use of feed in the breeding process to reduce the production of residual bait; Regularly test the pH value and water quality of shrimp ponds, find problems in time and take measures; Choose the right breeding species and density, avoid overloading shrimp ponds, etc.
