Hayward CL200EF Automatic Chlorine Feeder for In-Ground Pools — 9 lb Capacity, Adjustable Dial

The Hayward CL200EF is an in-line, offline automatic chlorine feeder that delivers steady, adjustable tablet sanitation for residential in-ground pools with up to 9 lb tablet capacity.

Keeping pool water clear and properly sanitized shouldn’t require daily attention. The Hayward CL200EF simplifies routine pool care by metering chlorine tablets into your circulation system via an offline in-line installation. Built from chemical-resistant materials and featuring a user-adjustable control dial, this feeder is engineered for long service life and predictable sanitizer delivery so pool owners can maintain balanced water with fewer interventions.

How does the CL200EF manage chlorine distribution for my pool?

The CL200EF provides a continuous, controlled release of chlorine tablets into an offline plumbing loop, maintaining more consistent residual sanitizer than occasional manual dosing. The adjustable control dial lets you fine-tune output to match pool volume, bather load, and seasonal needs.

• Metered tablet dissolution via inline/offline plumbing for steady sanitizer levels
• Adjustable control dial for precise feed rate
• Compatible with most residential circulation systems when installed per guidelines

What capacity and build quality can I expect from this chlorinator?

This feeder holds up to 9 pounds of standard chlorine tablets, reducing refill frequency for typical backyard pools. Its corrosion-resistant housing and rugged construction resist chemical exposure and outdoor conditions to provide durable operation season after season.

• 9 lb tablet capacity supports longer service intervals between refills
• Chemical-resistant materials designed for pool environments
• Engineered for reliable performance with other Hayward pool equipment

Is installation flexible and will it fit my existing equipment?

The CL200EF is intended for offline, in-line installations and integrates with a wide range of pump and circulation setups when installed according to Hayward instructions. Because it operates on a bypass loop, it minimizes direct exposure of the main plumbing to concentrated chemicals while allowing effective sanitizer introduction.

• Designed for offline/in-line plumbing configurations
• Works with many residential pool pump systems when installed properly
• Installation recommendations and plumbing layout improve safety and performance

How do I adjust output or maintain the unit during the season?

Routine maintenance is straightforward: refill tablets, inspect seals and fittings, and set the dial to achieve the desired residual chlorine. The precision control dial lets you respond to changes in weather, usage, or pool size without complex recalibration.

• Use the control dial to raise or lower sanitizer feed rate
• Periodic visual checks of housing, seals, and tablet levels recommended
• Refill the hopper with standard chlorine tablets as needed (up to 9 lb capacity)

Who is this for: The Hayward CL200EF is aimed at residential in-ground pool owners and DIY installers who want reliable, low-maintenance sanitation. It’s a good match for homeowners upgrading from manual tablet dosing or adding an automated feeder to an existing hydraulic layout, especially when steady chlorine delivery and durable construction are priorities.
