The chemical balance of the swimming pool is an important part of ensuring the safe use of the swimming pool. Among them, the chlorine content of the swimming pool is one of the important indicators for measuring the water quality of the swimming pool. The chlorine content of the swimming pool is usually tested by free chlorine test strips or test kits. The results are expressed by color changes. Abnormal colors (orange or other non-standard colors) may appear during the test, which may cause concerns among swimming pool managers. This article will analyze this issue.
First, we need to understand the principle of free chlorine testing:
Test principle: The free chlorine test of the swimming pool usually adopts the colorimetric method, that is, the test liquid reacts chemically with the free chlorine in the pool water to produce color changes, and then the resulting color is compared with the standard colorimetric card to obtain the concentration of free chlorine in the pool water.
Color change: Generally speaking, the color change of the test liquid is positively correlated with the concentration of free chlorine in the pool water. When the free chlorine concentration in the pool water is low, the color of the test liquid will be lighter; as the free chlorine concentration increases, the color of the test liquid will gradually deepen.
Reasons and solutions for orange color:
1. The chlorine content in the swimming pool is too high and the chlorine disinfectant is added excessively.
When adding chlorine disinfectant, excessive chlorine disinfectant is added due to miscalculation or improper operation. As a result, the free chlorine content in the swimming pool is too high, exceeding the normal level.
Solution:
First, stop adding chlorine disinfectant. The most direct way is to change a lot of water and dilute the high concentration of chlorine with fresh tap water. And increase the circulation strength of the circulation system to accelerate the consumption of free chlorine. You can also change the water.
2. Expired or ineffective reagents:
Improper storage of reagents: Long-term exposure of reagents to high temperature, humidity, or sunlight will cause ineffectiveness.
Expired reagents: The accuracy of expired reagents is reduced, and the reliability of test results cannot be guaranteed.
Preventive measures
Test water quality regularly: It is recommended to test water quality at a certain frequency, including indicators such as free chlorine, pH, and alkalinity.
Strictly follow the instructions: When adding disinfectants or other chemicals, be sure to strictly follow the operating steps in the product instructions. Calculate the precise amount to ensure that the chemical level of the swimming pool is kept within the normal range.
Keep the pool clean: Clean the debris in the pool regularly and keep the environment around the pool clean.
Choose the right chlorination method: According to the actual situation of the pool, choose the right disinfection method, solid chlorine, chlorine generator, etc.
When the test result of your pool’s effective chlorine level turns orange, don’t worry. Troubleshoot according to the above method and find out the problem. You can solve it quickly. At the same time, strengthening daily maintenance and management is also an important means to prevent such problems from happening. As a professional swimming pool chemical manufacturer, I hope my experience can enable you to have a healthy and beautiful swimming pool.
