FAQ
Our expert staff answers customer's most asked questions.
Can I use a salt cell with a sand filter?
Yes, a salt cell can be used with a sand filter. In fact, the two work perfectly together — the filter clears debris from the water, while the salt system sanitizes it for a clean, balanced pool.
What types of pool heaters are available?
There are several types of pool heaters, including gas heaters, electric heat pumps, and solar heaters. Each type has its advantages, so consider factors like installation costs, energy efficiency, and your pool usage patterns when making a choice.
How does Shasta Pure work?
Shasta Pure uses a combination of oxygen and nanobubbles to purify pool water. This natural process sanitizes the water effectively and provides a clean and safe swimming environment without relying on traditional pool chemicals.
