7. TOOLS NEEDED
8. POOL PREPARATION
Please ensure that your pH is balanced to the recommended level for your swimming pool surface.
Ideal pH Levels:
A pH of 8.0 makes your chlorine only about 26% efficient so that is why it is critical to keep your pH in
range. A correct pH level must be maintained to prevent problems such as black spot, staining, cloudy
water etc. An incorrect pH level can damage the surface finish and walls of your pool.
When pH is high you can add Hydrochloric Acid to lower the pH level. When pH is low you can add
sodium bicarbonate (soda ash) to increase the pH level.
