I bought a demo/open box chlorinator from them. So far the product has been working well (one week) and it looked new in the manufacturers box when I got it. Communication with them was great. Price I got for the open box item was worth it. Would use them again. Thanks.

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.
Can you change a LED pool light without draining water?
No, typically you don't need to drain the pool to replace an underwater light. Most LED fixtures allow for bulb replacement while submerged, but ensure the power is off before proceeding.
How do I maintain my pool heater?
Regular maintenance is essential for optimal performance. This includes checking the heater's pressure, cleaning filters, and ensuring that the water chemistry is balanced. Consult your heater's manual for specific maintenance guidelines.
