Hayward CL100 Automatic Chlorine Feeder — Inline 3-inch Tablet Dispenser, Corrosion‑Proof

The Hayward CL100 Automatic Chlorine Feeder is a durable, corrosion-proof in-line dispenser that automatically doses 3-inch chlorine or bromine tablets to help maintain pool and spa sanitizer levels with adjustable feed control.

The CL100 attaches to your circulation system and uses standard 3-inch tricolor tablets to provide steady chemical distribution without constant manual dosing. Built from corrosion-resistant materials, this model is designed for straightforward do-it-yourself installation and low-maintenance operation. Its simple controls and secure lid make refilling and adjustments fast and predictable for both new and established pool setups.

How does the CL100 regulate sanitizer delivery?

The unit controls the amount of chemical released through a dial-operated valve that adjusts flow from the feeder into your plumbing. Turn the dial to change the rate of tablet exposure to water, letting you match output to pool size and usage patterns without complex programming.

• Compatible with standard 3-inch tricolor sanitizer tablets
• Works inline with your pump and filter circulation
