What Affects My Swimming Pool Water Chemistry?

Even with excellent care and maintenance, a swimming pool’s chemistry can still get out of balance. Your water chemistry is constantly changing due to environmental factors, usage, weather, and even the kinds of floats you use in the pool. Learn five factors that play a major role in your swimming pool water chemistry, and how you can control common issues in this area.

Swimming Pool Water Chemistry: pH Balance

pH is the major factor you should keep balanced when maintaining your swimming pool water chemistry. pH refers to the level of acidity in your water, and comes from the use of chemicals to keep it free from contaminants and algae growth. You want your pH to remain between 7.4 to 7.6 at all times to avoid burning eyes and to allow for free chlorine use.

Swimming Pool Alkalinity

Closely connected to pH, the alkalinity is the amount of base, or hydrogen ions, in your water. It also refers to the ability of your water to contain and reduce the loss of hydrogen. Keeping your alkalinity balanced helps to keep your pH levels optimal when additional acids or bases are introduced to the water. You want your pool’s alkalinity to be between 80 to 150 parts per million (PPM).

Pool Water Calcium Hardness Levels

Your pool has dissolved calcium salts in its water. These can increase or decrease from the oils and salts on people’s skin, from debris that falls into your pool, and from the chemical reactions that form from maintaining your water’s balance. You want to keep these levels around 250 ppm. If the calcium level is too low, it can create the potential for surface blemishes, while high amounts of calcium make the water cloudy and can result in scaling.

TDS (Total Dissolved Solids) in Your Swimming Pool

When a pool has been in use for a long time, things like suntan lotion, chlorides, dirt, debris, algaecides, and other contaminants can be introduced into the water from leaves, tree bark, dirt, skin chemistry, and other factors. TDS can’t be avoided, but it should be kept under 450 ppm.

Pool Chlorine Levels

Chlorine is, for many people, a vital part of keeping the chemistry in their water properly balanced. Too much chlorine, and you’ll end up with burning in the eyes and a strong odor. Too little, and the pool’s alkalinity and pH will be out of control, leading to things like cloudy water and algae growth. Ideal chlorine levels should be at 0.2ppm or less, and free chlorine should be in the range of 1 to 3 ppm.
