Part # W28001
Replacement Cartridge for DuoClear Sanitizing System
Powerful Nature2 replacement cartridge uses natural minerals to sanitize your pool and reduce the need for chlorine. This cartridge for the 35k gallon DuoClear System contains silver to kill bacteria and copper to fight algae, requiring only 0.5 ppm of chlorine for complete sanitization. Reduces the smell and irritation chlorine can cause and gives pool water a soft, silky feel.
This easy-to-replace cartridge lasts six months under normal operating conditions. The cartridge should not be used longer than six continuous months. To ensure health and safety, replace the DuoClear cartridge promptly; your pool will not be sanitized properly by the chlorination alone, even at full output. The DuoClear system requires sufficient residual silver from the cartridge to sanitize effectively.
Note: The Duoclear 35 replacement cartridge can be used on the Duoclear 25 (25,000 gallon) or Duoclear 45 systems (45,000 gallaon). If you are using the Duoclear 35 on a Duoclear 25 system then the cartridge will last a little longer than 6 months and if you are using the Duoclear 35 on a Duoclear 45 system then the cartridge will last a little shorter than 6 months.

I'm not sure if I need the ionizer part W28000, W28001 or 28002. All three are listed on the body of the filter (or whatever you call it) that houses the ionizer. Please advise. :)

Pros: Crystal clear water
Cons: Only lasts 6 months
After opening my pool for the new season and getting all the chemicals balanced the water still looked a bit cloudy. I remember I needed a new dura clear cartridge, after install the new one the pool was crystal clear. This product makes a noticeable difference in the clarity of the water.
