This is the review I just left on Google: I recently needed a specialty paint that was not easy to find. I found it at TS Pool Supply online. After sending an email to inquire, I got an immediate response. The help I was given that followed was amazing! I worked with Zachary Brown. He was patient, efficient and responded to all of my questions quickly. Then even arranged to get the paint transferred to another store on the same day for easier pick-up. The product, the price, and especially the service, were the best ever!

FAQ
Our expert staff answers customer's most asked questions.
Can multiple discounts be added to an order?
The application of multiple discounts varies depending on ongoing promotions. In most cases, our quotes already include the lowest possible price with all available discounts applied. Contact our sales team for the most up-to-date promotional offers.
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.
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.
