What our customers are saying
Our pool water is very clear. I wasn't really expecting this from the Shasta Pure unit... I feel like our pool is more clear looking, its kinds like swimming in drinking water...

Shopping with Shasta was an excellent experience. I followed a link from an email from Shasta for a salt cell for my pool, which I needed. They advertised an open box deal which was hundres of dollars less expensive than anywhere else I could find the equivalent part for online.
I accidentlh placed an order for the part to pick up at the wrong location. Communicating through email, Zachary and Chuck quickly resolved the problem and changed the location to the location closer to my home.
I've also shopped for pool deck paint from Shasta. Not only was the price better than anywhere else I could find online, the product was available quickly from my store.

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.
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.
