How to lower the pH value of a swimming pool?

Lowering the pH value of a swimming pool can be achieved in several different ways. Here are some common methods:

Using a pH reducer

Using a pH reducer is one of the most direct and effective methods. This type of agent is usually a high-purity acidic substance that can quickly reduce the pH value of the pool water. When using, add this product at a dosage of 15 grams per cubic meter of water for every 0.5 degree pH value reduction, that is, 1.5 kg of this product is required for 100 cubic meters of water to reduce the pH value by 0.5 degrees. Dilute this product with water and sprinkle it directly on the pool surface.

Slow-release method

The slow-release method is a method of adjusting the pH value by adding substances that can slowly release acid and alkali to the water. Commonly used slow-release substances include coral sand, volcanic rock, olive leaves, sunken wood, black water, etc. This method is very effective for slightly alkaline or acidic water and can be used alone. For hard alkaline water, the effect is poor and it should be used in conjunction with other methods.

Softening method

The softening method is a method of replacing the water in the fish tank with softened water several times. This method has a narrow scope of application and is generally only applicable to hard alkaline water with a high pH value. After a period of replacement, the hardness of the fish tank water will decrease, the buffering capacity will decrease, and natural codification will occur, which is what we really want to see.

 


Biological method

The biological method is a biological method that affects the acid production of bio degradation by adjusting the number of various organisms. The final products of bio degradation in the fish tank are mineral salts, water and carbon dioxide. Due to the presence of carbon dioxide and mineral salts (mainly nitrates), the water will be acidified. Common means of biological methods include: increasing or decreasing the number of fish, feeding amount, the amount of filter material, cleaning or replacing new filter material, etc. Through these means, we can increase or decrease the number of terrifying bacteria and control the amount of acid production.

In summary, there are many ways to reduce the pH value of the swimming pool, and which method to use depends on the specific situation and personal preference. Before implementing any pH adjustment, water quality testing should be carried out to ensure that the pH adjustment is within a safe range.

The working principle of carbon dioxide detector

图片
The working principle of carbon dioxide detector The working principle of the CO2 detector is mainly based on the infrared light source absorption principle. The following is the detailed working mechanism: Infrared absorption principle: Carbon dioxide detectors detect carbon dioxide gas in the environment through the absorption properties of infrared light sources. Specifically, carbon dioxide molecules have absorption properties for infrared light of specific wavelengths, especially infrared light with a wavelength of approximately 4.26 microns (4260 nanometre ). Measuring chamber and light source: The gas to be measured is introduced into a measuring chamber with an infrared light source mounted at one end of the chamber and a filter and detector at the other end. The filter allows infrared light of a specific wavelength to pass through, while the detector measures the luminous flux through the chamber. Detector Measurement: The amount of light flux received by the detector depends...

Introduction of temperature and humidity data recorder A temperature and humidity data logger is a device used to monitor and record changes in temperature and humidity in the environment. It has an important role in many areas, such as: In the laboratory, it can ensure that the experiment is carried out under the appropriate temperature and humidity conditions to ensure the accuracy of the experimental results. In the storage place, it helps the management to monitor the temperature and humidity inside the warehouse to prevent the goods from getting damp or mildew. In the production workshop, the temperature and humidity of the production environment can be monitored to ensure the normal progress of the production process. Type of temperature and humidity data logger Digital temperature and humidity recorder Features: The temperature and humidity data in the environment is collected by the sensor and displayed in digital form. This type is more common, simple and intuitive operation,...

  The Importance of Weather Forecasting Weather forecasting has an extremely important impact on our daily lives, economic activities and social security. The following are some of the main aspects: 1. Prevention of natural disasters Weather forecasts can predict possible weather disasters in advance, such as heavy rain, typhoons, snowstorms, etc., so as to take appropriate precautions to reduce the loss of life and property.   2. Planning life and production activities People can understand the future weather changes through the forecast, reasonable planning of travel, tourism, outdoor activities, etc., to improve the convenience and safety of life. For agricultural production, weather forecasts can provide farmers with references for agricultural activities such as sowing, fertile  application, irrigation, etc., so as to improve the efficiency of agricultural production and yield.   3. Emergency response When emergencies occur, such as epidemics, earthquakes, etc.,...
