FAQ
Our expert staff answers customer's most asked questions.
How frequently should I clean my filter cartridges?
The cleaning frequency is contingent on your filter's size. As a general guideline, initiate the cleaning process when the filter pressure exceeds the initial pressure by 10 psi. This ensures optimal filtration efficiency.
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.
Does a solar panel for my pool effectively save energy?
Absolutely! The installation of a solar pool heater can significantly reduce your swimming pool heating costs, providing an energy-efficient solution.
