How does the IntelliChlor Plus40 compare to other salt chlorine generators?
The Pentair IntelliChlor Plus40 delivers faster, steadier chlorine production than standard salt systems. Additionally, it uses advanced onboard diagnostics, real-time salinity monitoring, and oversized titanium blades that maintain output even during heavy swim season. Furthermore, the simple LED interface and one-button controls make it easy for any pool owner to manage. While the durable cell design helps extend lifespan and reduces long-term operating costs.
Pro Tip: Size up when possible — choosing the Plus40 instead of a smaller cell lets you run at lower output settings, which improves efficiency and maximizes cell longevity.

FAQ
Our expert staff answers customer's most asked questions.
What is the difference between E-commerce (EC) and Trade pricing?
E-commerce pricing is our standard online retail pricing available to all customers. Trade pricing is exclusively for pool maintenance professionals and typically offers better rates. To get Trade pricing, you'll need to request a personalized quote.
What is better for my pool and my body: Salt Chlorinator or Chlorine Chemicals?
Opting for a salt chlorinator is a superior choice for both your pool and skin. In addition to cost savings on chemicals, it requires minimal maintenance with a 5-7 year replacement cycle on salt cells. Most salt cells have an operating life of 10,000 hours. Proper maintenance will help extend the life cycle of salt cells. Refer to your owner's manual for cleaning instructions and tips on cleaning Pentair salt cells and products that help keep all salt cells cleaner. Explore our recommended models, Gentle Chlor and IC-40, by following this link.
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.
