FAQ
Our expert staff answers customer's most asked questions.
What are the ideal chemical ranges for my pool?
Achieving a balanced pool involves maintaining a pH range of 7.2–7.8, total alkalinity between 80–120 ppm, calcium hardness at 180–220 ppm, and cyanuric acid (stabilizer) within 30–50 ppm. Chlorine levels should consistently fall within the 1–3 ppm range, by may need to be increased as CYA levels go above 60 PPM.
How often should I test my pool water?
Regular testing, ideally once a week, ensures that chemical levels are within the recommended range. This practice ensures that your pool is always ready for enjoyment.
