Lowering the pH of water can be achieved in a variety of ways, depending on your application scenario and personal preference. Here are a few common methods:

Using Terminable catalpa leaves

Terminator catalpa leaves are one of the most commonly used items to lower pH. Collect the dried Terminal catalpa leaves, bundle them up and put them in the water. When they slowly rot, they will begin to release calico acid, humid acid, etc., making the water gradually acidic.

Using pineapple peel or pineapple flesh

Pineapple peel or pineapple flesh has the effect of lowering pH. It contains organic acids, amino acids, etc., which will slowly release these substances when put into water.

Using driftwood

Driftwood can lower the pH of the water, but it will also cause the water to turn yellow, which may affect the appearance. Usually, the driftwood needs to be boiled for a period of time and then cooled before being put into the tank.

Using chemical reagents

Using hydrochloride acid to lower pH is a quick and effective method, but the required amount needs to be accurately calculated, because using a large amount of hydrochloride acid may cause a rapid and significant drop in pH, which may cause stress reactions in farmed animals.

Use sodium hydrogen phosphate

Sodium hydrogen phosphate is weakly acidic, which can not only lower the pH value of water, but also add nutrition to fish after melting water. In addition, acetic acid, vinegar, etc. can also be used to lower the pH value.

Increase the carbon dioxide content in water

When carbon dioxide dissolves in water, it forms carbolic acid, which lowers the pH value of water. This can be achieved by increasing the aeration of the water body, because more carbon dioxide is brought in during the aeration process.

Biological regulation method

Using biological regulation methods to lower the pH value of fish ponds is an environmentally friendly and sustainable way. These organisms can produce acidic substances through metabolic activities, thereby lowering the pH value of fish ponds. At the same time, they can also improve water quality and improve the ecological environment of fish ponds.

The above methods have their own advantages and disadvantages. Which method to choose depends on your specific needs and conditions. Before implementing any pH adjustment measures, it is recommended to test the pH value of the water sample and continue to monitor it throughout the process to ensure that the results are as expected.
