Pool water testing factors and safety level

There are some factors that you should keep in mind while testing the pool water. The healthy levels of these factors ensure that the pool water is good enough for you to swim. These various factors are:

Chlorine levels

When we think about clean pools, chlorine comes to our mind. This is because chlorine helps to keep the water free from bacteria and germs. The ideal level for this factor is 1.0-3.0 ppm.

Bromine levels

In a swimming pool, the bromine level should be around 5 ppm and never below 3 ppm. Therefore, bromine is usually used as an alternative to chlorine.

pH levels

The pH level of the water states its acidity or alkalinity levels. Ideally, the pool water should have a pH level of 7.2-7.8 as the chlorine performs best at these scales.

Total alkalinity

The recommended level of alkalinity for a pool is between 100-150 ppm. When a pool has the perfect alkalinity, it stands for a good pH level, and the water wouldn’t irritate.

Calcium hardness

Calcium is an important mineral component for water defining its hardness. Therefore, you want the calcium level to be between 200-400 ppm. A pool usually appears cloudy when there is too much calcium in it.

Cyanuric acid

The recommended level of cyanuric acid in a pool is below 100 ppm. This acid acts as a stabilizer for the pool and helps it to remain clean and fresh

Longtime users may buy different digital kits for regular pool maintenance. Some people still prefer to use liquid test kits because of its cost-effective factor.

State of Pool and Accuracy
