DEL's CDS-16 natural spa sanitizer uses CD chip ozone technology to bring you affordable, reliable ozone that fits smaller spas up to 400 gallons.

Renewing your CDS-16 is easy and inexpensive with DEL's 9-0720-01 Renewal Kit.  Reduce waste and save money.  Talk about Going Green!

The Spa Eclipse ™ and CDS-16 are the same technology, different box.  If you only need a 110V Spa Eclipse™ do yourself (and the environment) a favor and choose the more eco-friendly, compact CDS-16.
