Are you one of them? So how do we tell if the water in a swimming pool is good or bad?

 

Look 

If the residual chlorine content is normal and the water is good, the pool water will appear bright light blue. If the water is white, slightly cloudy, then the number of bacteria may exceed the limitation.

There is no sediment at the bottom of the pool. The water should be clear and transparent to the bottom. The dissipating time of the foam in the pool should be within 15 seconds, indicating that the water is often changed and relatively clean.

 

Smell 

If you can smell chlorine, it's ok. If the medicine tastes too strong and even choked people, the effective chlorine concentration may exceed the standard.

 

Ask

Good water will feel soft, if the feeling of hard, astringent, or even have cancer itching feeling, water quality may be poor. It is better to ask people around about the swimming pool evaluation, to understand the relevant information.
