Ordered an open box salt cell and it arrived quickly and in perfect shape. Literally, the only thing that made it open box was the security seal on the box was cut. Great price on a new salt cell. Thank you!

FAQ
Our expert staff answers customer's most asked questions.
What are the benefits of a DE Filter?
There is a huge benefit to using a DE (Diatomaceous Earth) filter, DE filters have superior filtration, and can trap particles as small as 2-5 microns. This results in exceptionally clear and clean water. This high level of performance is ideal for removing fine debris like pollen and algae. Additionally, this can potentially lead to reduced chemical usage because more contaminants are removed from the water.
Are there any specific considerations for saltwater pools?
Yes, saltwater pools require pumps that are compatible with saltwater systems. Look for pumps made from corrosion-resistant materials to ensure longevity and efficiency in saltwater environments.
What is the recommended duration for running my pool equipment?
There isn't a specific timeframe, but it's essential to complete a full water turnover within a 24-hour period. Utilizing pool equipment during off-peak hours can be cost-effective.
