FAQ
Our expert staff answers customer's most asked questions.
Can you add pool automation to an existing pool?
Absolutely, pool automation systems can be easily added to existing pools. You can start with a basic system that controls your filter and pump. Eventually, upgrade to include features like lighting and water features as needed.
How many HP pumps do I need for a pool?
The horsepower (HP) of your pool pump should match your pool size and flow rate, which usually ranges from 40 GPM to 80 GPM. Generally, pool pumps range from 0.75 HP to 3 HP. Opting for a higher GPM flow rate can help reduce wear and tear on your pool equipment.
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.
