Can You Swim In A Green Pool?

The question you are asking your self is can I swim in a green pool? The answer is NO. In this article, I will explain why pool water turns green and what that water can do to you if you swim in it.

Why Does Pool Water Turn Green?

1 There is an imbalance in the PH levels of the pool water.
2 The Chlorine levels are too low.
3 The alkalinity levels are too low.
4 The Oxidized Metal quantities example copper is too high. (High acid levels, Metal Components in pool equipment, Copper heater elements)
5 Excessive quantities of Pollen are in the water.

Here’s Why You Should Not Swim In A Green Pool

When your pool is green that means there is an imbalance in the PH levels of the pool. If the PH levels are out this means that the pool water is not sterilized.

When the pool water is not sterilized there is an opportunity for algae, bacteria, and pathogens (microorganisms that can cause disease) to be present and grow.

If this is the case, then if a swimmer has an abrasion on their skin, there is a potential for infection and a possibility of incurring a rash or folliculitis (inflammation of hair follicles).

If the pool water has any form of algae and bacteria in it, it will be the ideal breeding ground for mosquitoes and other insects that thrive in these conditions.

Excessive amounts of oxidized metals can turn a swimmers’ hair green and there is a good possibility that your pool walls will be stained.

High levels of the copper content in the pool water can irritate your mouth, eyes, and nose, cause headaches, nausea, vomiting, stomach cramps, dizziness, and diarrhea.


It is not advisable to swim in a pool with water that is any color than clear blue. There are too many health problems that a person can incur from swimming in a green pool.

Rather sort out the PH levels first. Get the pool water crystal clear so that you and your family can enjoy the pool with no issues.
