Swimming Pool Chemicals 101

Learn the Basics!

Yes! Your backyard swimming pool is finally ready!

1. Your pool water’s pH

pH measures how acidic or basic a substance is, on a scale from 0 to 14. A pH of 7 is neutral, while any number above 7 is basic and any number below 7 is acidic. Your pool water’s ideal pH level is 7.4 to 7.6.

pH levels are easily affected by numerous factors: rain, leaves, people etc. This is the reason you need to test your water’s pH level regularly. Keep the right balance with a pH increaser – such as Soda Ash – or a pH decreaser – such as Dry Acid – depending on the situation!

2. Total alkalinity

Since pH levels are easily affected by external factors, a moderator that keeps them more stable is essential for preventing drastic fluctuations. This is what total alkalinity is all about! Your pool water’s ideal alkalinity level is 100-150ppm.

Remember to always adjust total alkalinity levels first, before balancing your pool’s pH levels, since alkalinity works as a “pH protector” for the water. For balancing alkalinity levels, you can use the same chemicals you use for your water’s pH levels – Soda Ash and Dry Acid!

3. Chlorine level

Chlorine is by far the most popular pool sanitizer! It’s effective – and cost effective. It will keep your pool clean from bacteria, viruses and algae! Your pool water’s ideal chlorine level is 1-3ppm.

Chlorine comes in various forms – liquid, tablets, sticks and granules!

4. Calcium hardness

Calcium hardness measures how hard or soft the water is. Your pool water’s ideal level for calcium hardness is 150-400ppm, depending on the pool’s building materials.

Anything higher or lower can harm the pool’s equipment and affect the water quality. The right chemicals and regular testing will help you keep the calcium hardness level just right for your pool water!

5. Algaecide

Although chlorine usually keeps your pool free from algae, an algaecide acts as your backup when chlorine levels are unbalanced and algae starts to spread.

Experts suggest using your algaecide after a shock treatment – i.e. super-chlorinating the pool with a high dosage of chlorine all at once. This treatment is an important part of your pool maintenance routine and helps keeping the water clear and clean!
