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.
When do I need to change my sand?
For best performance, replace the sand in your Hayward ProSeries 22" Filter every 3–5 years. However, if you notice cloudy water, faster pressure build-up, or frequent backwashing, it may be time for a change sooner.
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.
