Product details

The Unicel C-8412 is a 120 square foot pleated replacement cartridge. It replaces the Hayward® CX1200RE used in the Star Clear Plus, and it is the cartridge for the Waterway Pro Clean 125 and the Waterway Clearwater II 125.

Why the surface area matters

A cartridge filter works by spreading flow across as much media as possible. The pleats are what fit 120 square feet into a tank you can lift. Fit a cartridge with less area, or one that has collapsed pleats, and the same flow is forced through less media, which raises pressure, shortens the run between cleanings and pushes dirt deeper into the fabric.

Cleaning and replacing

Pull the cartridge when the gauge sits roughly 8 to 10 psi above its clean reading. Hose the pleats from the top down so debris washes out rather than in, then soak it in a cartridge cleaner to strip the oils and scale a hose cannot touch. Once cleaning stops bringing the pressure back, or the pleats tear and the end caps loosen, the cartridge is done.

Questions and answers

What people ask about this product, answered by our pool techs.

Which filters does this cartridge fit?
It replaces the Hayward® CX1200RE in the Star Clear Plus, and it is used in the Waterway Pro Clean 125 and the Waterway Clearwater II 125.
How much filter area does it have?
120 square feet.
How often should it be replaced?
Clean it whenever the pressure climbs about 8 to 10 psi over the clean reading. Replace it when cleaning no longer brings the pressure back down or when the pleats are torn, flattened or the end caps have separated.
Can I clean it instead of replacing it?
Yes. Hose the pleats out from the top down, then soak it in a cartridge cleaner to lift oils and scale. A cartridge that has been cleaned properly still fails eventually as the media loses its structure.
