Hayward CL200EF in-line Automatic Chemical Feeder - Reliable Tablet

In this review of the Hayward CL200EF in-line Automatic Chemical Feeder the bottom line is clear: this is a straightforward, durable feeder best suited to owners of small to mid-size pools who want hands-off tablet chlorination or bromination. The reviewer found the updated model keeps sanitizer levels steady with minimal fuss, thanks to a simple dial control and an Easy-Lok cover that makes tablet changes quick and secure. Installation is typically simple for anyone comfortable with basic PVC plumbing, and the robust ABS body and Viton seal suggest long service life.

Key Features

• Tablet Compatibility: Accepts large or small slow-dissolving tablets so users can choose their preferred sanitizer format.
• Feed Rate Control: The dial control valve allows precise adjustment of chemical feed rate to match pool size and sanitizer needs.
• Secure Access: Easy-Lok threaded cover and a unique finger-release catch provide safe, convenient access and extra security when adding tablets.
• Durable Construction: The ABS body and high quality Viton seal improve resistance to pool chemicals and extend the unit's usable life.
• Inline Design: Designed for in-line installation which integrates cleanly with existing plumbing and is suitable for both new builds and retrofit installs.

Who It's For

The Hayward CL200EF is ideal for pool owners with small to mid-size in-ground or above-ground pools who want to reduce daily maintenance by automating tablet feed. It fits owners who prefer a mechanical dial adjustment over electronic controllers and who value a robust, chemical-resistant housing.

It is less suitable for very large commercial pools that require high-capacity feeders or for users who need remote monitoring or automated digital dosing. Customers who cannot perform simple PVC connections may prefer having a professional handle installation.
