Hayward CL200EF In-Line Automatic Chlorine Feeder
The Hayward CL200EF is an automatic inline chlorine feeder designed for in-ground pools but commonly adapted for extended above-ground setups with compatible fittings. It holds up to 9 pounds of chlorine tablets, enabling longer intervals between refills and steady sanitation. Its durable, corrosion-resistant housing supports long-term performance in pool environments. Best for homeowners who want a high-capacity feeder with minimal maintenance and reliable discharge consistency.
Best for: Pools that require steady, long-run chlorine dosing with fewer refills and a robust, corrosion-resistant body. Choose this if you value a proven brand and higher capacity in an inline design. Caution: Ensure proper inline compatibility with your above-ground plumbing fittings and confirm installation clearances before purchase.
HYDROTOOLS By SWIMLINE 8750 In-Line Chlorine Feeder
The HYDROTOOLS 8750 is an in-line automatic chlorinator with a 9 lb capacity and universal compatibility for above-ground and in-ground pools. It features simple, screw-on access and a straightforward output adjustment. It is well-suited for users who want a dependable inline feeder at a reasonable price with easy maintenance. Better for: pools needing a simple, economical inline chlorine solution with adjustable output.
Limitation: Some setups may require adapters to fit existing piping. Best use: alignment with standard 2-inch plumbing and compatible tablet sizes.
SeaSlep Off-Line Automatic Pool Chlorinator
The SeaSlep Off-Line Chlorinator operates independently from the pool pump, feeding chlorine to the water via a simple dial-based control knob. It has a 9 lb capacity and accepts large or small chlorine or bromine disks (tablets not included). Ideal for seasonal use or pools with variable occupancy, it allows fine-tuned dosing without constant supervision. Best for: above-ground or inground pools needing nuanced adjustment and straightforward off-line operation. Caution: verify compatibility with your disk type and ensure the unit is installed on a suitable return line.
MAYGO CL200 In-Line Automatic Pool Chlorinator
The MAYGO CL200 is an inline automatic pool chlorinator designed to work with above-ground and indoor pools. It handles up to 9 lb of chlorine tablets and features a 360-degree omnidirectional control knob to regulate water inlet and outlet flow. This model is best when inline installation is preferred, offering practical control without extensive modifications. Choose this if you need flexible inline compatibility and a broad adjustment range. Limitation: external thread sizing may differ from CL200; use appropriate connectors to fit your system.
RovPool Offline Automatic Pool Chlorinator
The RovPool 9 lb offline chlorinator provides a straightforward, beginner-friendly setup. It uses a dial-controlled output to adjust chlorine feed, and its 2-inch ports support quick water piping. Best for: homeowners who want an easy install with adjustable dosing in a compact, offline design. Caution: ensure adequate venting is not required and confirm compatibility with your pool pump configuration.
Buying Guide
What capacity do I need?
Large pools or high usage typically benefit from 9 lb feeders, reducing refill frequency. Smaller above-ground setups may get by with lower-capacity models or those that provide adjustable dosing to maximize tablet use.
Inline vs. offline feeders—which is better?
Inline feeders connect directly into the plumbing and can be tidier and more integrated. Offline feeders sit separately, often offering simpler installation and easy retrofits to existing systems. Choose based on your plumbing layout and willingness to modify piping.
How important is ease of adjustment?
Dial-based output controls let you fine-tune dosing without tools. This is helpful for seasonal pool use and varying member activity. Avoid models with hard-to-reach adjustment mechanisms if you have limited maintenance time.
What installation considerations matter?
Check compatibility with your pool’s piping size (2-inch vs 1-1/2 inch), thread types, and whether adapters are required. Verify that the enclosure is corrosion-resistant for long-term exposure to chemical cleaners.
Best practices for use and safety
- Follow tablet usage guidelines exactly as specified by the feeder’s manual.
- Regularly inspect seals and lids to prevent leaks or air ingress.
- Store chlorine tablets in a cool, dry place away from sunlight and pets.
Summary of key considerations
- Capacity aligns with pool size and maintenance frequency.
- Inline feeders save space but require compatible plumbing; offline feeders are easier to retrofit.
- Adjustable dosing is critical for balancing swimming season variability.
- Durability and corrosion resistance extend lifespan in harsh chemical environments.
