Here are some basic descriptions of the factors that can affect the quality of your pool water. Please note that all information is generic and will not apply exactly the same way to all swimming pools. Be sure to discuss any questions or concerns with your local pool professional.


Bathing Load
The more people that use your pool, the more disinfectant you will need to properly sanitize it and control algae.

Sunlight
The warmer the weather, the faster you will lose the residual disinfectant needed in the pool to control bacteria. You can make the residual last longer by maintaining the proper stabilizer level.

Water Temperature
Most pool chemicals will not last as long when water temperature gets warmer. The acceleration is even greater when the water temperature exceeds 85 degrees.

Wind & Rain
When you experience periods of wind & rain, these conditions will carry dust, bacteria and even algae spores into your pool. These will overwork your current chemicals, reducing their ability to properly sanitize your pool.

PH- When the PH level of your water rises, the ability of your pool water to disinfect bacteria will decrease. You need to maintain PH level in the 7.2-7.6 range.

Total Alkilinity
When Alkalinity level is below 80 PPM, this will affect the PH level and may cause staining in a plaster pool, or result in possible algae growth. When the alkalinity level is too high, above 130 PPM, cloudy water and scaling can occur.
