Any pool needs regular maintenance and cleaning. Water is a favorable environment for the reproduction of various microorganisms. They can get into the pool from the environment, and the sun stimulates their growth. When contaminated, the water begins to acquire a specific smell, becomes cloudy and can be dangerous for people swimming in the pool. In order to make swimming in the pool as comfortable, useful and safe as possible, you need to periodically analyze and monitor the condition of the water.
Checking pH level
For the effective operation of the preparations used for disinfection, as well as the safety of bathers, the pH must be at a level of 7.2 – 7.6. This can be controlled using special pH testers .
Testers are usually used to control:
- content of impurities and salts;
- acid-base balance;
- concentration of oxygen, chlorine, and other disinfectants.
A pool tester is one of the most important devices for anyone who has a pool, as it can be used to measure water parameters and monitor its condition.
Testers can be:
- photometric;
- tablets;
- drip;
- electronics.

Some of the most popular among users are tablet and drop testers, their price is quite low and they are extremely easy to use. Photometric and electronic models of testers are extremely accurate and versatile. With their help, you can measure not only the pH level in water, but also determine the level of hardness, bromine, salt, chlorine and other indicators.
Water tests should be carried out based on the instructions included with the product. Most often, this simply involves taking water from the pool, placing it in a special measuring flask and lowering the test into it. After the reaction occurs and the test turns a certain color, it should be compared with the scale specified in the instructions.
If the pH value is too high, the water will become hard and people who swim in it may experience irritation of the mucous membranes, and the effectiveness of chemicals used to purify the water will be significantly reduced.
You can bring the pH level to the required value using special preparations . To lower the pH indicators, it is best to use the pH-minus liquid. This preparation is convenient to use with automatic dosing stations. For home use, the best option is the dry pH-minus regulator. To increase the pH indicators, you need to use special pH-plus granules.
Checking chlorine levels
Chlorine is necessary for the effective removal of various contaminants, as well as the destruction of dangerous bacteria. At its standard content in water, this element begins to disintegrate into compounds that are safe for equipment and the human body.
High chlorine levels can cause:
- reduction in the effectiveness of reagents that were introduced for disinfection;
- discoloration and damage to the soft bowl of the pool;
- lesions of the mucous membrane and skin;
- equipment failure.
Due to the lack of chlorine, microorganisms dangerous to health may begin to develop. Therefore, it is necessary to constantly monitor its indicators. The standard value for chlorine is 0.6-1.5 mg / l. Testers can help to find out what the level of free chlorine is. You need to collect some water from the pool in a measuring flask and add a reagent to it, the water should then be colored a certain shade. The color of the water must be compared with the table of values that comes with the tester. In order to determine the parameters as accurately as possible, you need to use electronic testers or sensors.
Disinfectants containing chlorine are an effective, high-quality and inexpensive way to treat water. They are classified into products for long-term and shock water treatment. To carry out stabilized regular cleaning, it is necessary to use long-acting chlorine, which has a higher concentration.
Determination of the level of active oxygen in water
Active oxygen is a powerful natural oxidizer that can effectively destroy viruses and bacteria without changing the taste and smell of water, it also does not cause any allergic reactions and is absolutely safe for the human body.

HTH Active Oxygen in Tablets is an oxygen-containing fast-dissolving preparation that can effectively and quickly destroy viruses and bacteria. This method is considered the most gentle option for disinfecting water. This product is well suited for children’s pools, home ponds and cases where it is not possible to use chlorine.
If you decide to use oxygen disinfection in your pool, you need to purchase special testers for active oxygen. The standard value for active oxygen is 3-8 mg/l. If the content is higher than this value, it can cause burns to the mucous membrane and skin, and if the content is lower, water disinfection will be ineffective.
