More Details on Our Top Picks
Hayward CL200EF In-Line Automatic Chlorine Feeder for In-Ground Pools
The Hayward CL200EF stands out as the best overall choice for in-ground pools due to its high capacity and reliable automation. Its 9-pound chlorine tablet capacity means fewer refills, which appeals to pool owners seeking convenience. Its corrosion-resistant housing ensures durability over years of use, especially in harsh pool environments. Compared with the U.S. Pool Supply model, the CL200EF offers more precise adjustable output, but it requires proper installation and may need plumbing adjustments. While it excels in consistent chlorine delivery, improper setup can lead to performance issues. This feeder is ideal for those who prioritize long-term durability and minimal maintenance. The main tradeoff is that it’s designed for offline plumbing, limiting application flexibility.
Pros:- Automated chlorine dosing for consistent sanitation
- High capacity reduces frequent refills
- Corrosion-resistant, durable construction
Cons:- Requires proper installation for optimal performance
- Limited to offline plumbing configurations
Best for: In-ground pool owners seeking a durable, high-capacity, automated solution with minimal refilling.
Not ideal for: Homeowners with above-ground pools or limited plumbing experience, since installation can be complex.
- Capacity:9 lbs
- Installation Type:In-line offline
- Material:Corrosion-resistant housing
- Compatibility:Supports various pool circulation systems
Our verdict“This feeder is best for in-ground pool owners wanting reliable, low-maintenance chlorine automation with long-term durability.”
R171096 Pool Chlorinator, 320 Automatic In-Line Chlorine/Bromine Feeder Compatible with Rainbow 320
The R171096 offers a compelling balance of affordability and functionality, making it ideal for budget-conscious pool owners. Its compatibility with the popular Rainbow 320 model ensures easy replacement without compatibility worries. Its adjustable flow control provides tailored chlorine or bromine output, similar to the Hayward CL200EF, but at a lower price point. The enclosed design enhances safety, and its corrosion-resistant ABS housing withstands pool chemicals well. However, installation might require some plumbing adjustments, and its capacity is limited to specific tablet sizes, which could mean more frequent refilling for larger pools. For owners managing pools up to 70,000 gallons, manual monitoring is necessary to maintain proper chlorine levels.
Pros:- Compatible with popular models like Rainbow 320
- Adjustable flow for customized output
- Safe enclosed design prevents contact with tablets
Cons:- Installation may require plumbing modifications
- Capacity limited to specific tablet sizes
- Requires manual monitoring for optimal performance
Best for: Pool owners needing a cost-effective, compatible replacement for Rainbow 320 or Pentair feeders.
Not ideal for: Users with complex plumbing setups or those seeking a fully automated, hands-off system for large pools.
- Capacity Range:6,500–70,000 gallons
- Tablet Support:up to 11 large or 98 small tablets
- Material:ABS
- Fittings:2″ slip PVC, 1.5″ adapters
- Warranty:12 months
Our verdict“This model suits budget-conscious pool owners wanting reliable, adjustable dosing compatible with popular systems, but it demands manual oversight.”
CL200 Inline Chlorinator Replacement for Hayward CL200 Pool Chlorine Feeder
The CL200 Replacement is designed for those who already own a Hayward CL200 but need a durable, easy-to-install upgrade. Its high-grade ABS construction and Viton seals promise longevity, matching the original’s performance while potentially offering better sealing and material quality. The adjustable feed rate allows precise chlorine control, similar to the Hayward CL200EF, but with a focus on ease of installation and safety—thanks to a finger release latch. It’s suitable for pools up to 40,000 gallons, making it ideal for residential pools. Nonetheless, reading instructions carefully is essential, as improper setup can impair its effectiveness.
Pros:- High-quality ABS and Viton seals for durability
- Easy installation with 2-inch fittings
- Adjustable chlorine feed for precise control
- Safe operation with finger release latch
Cons:- Requires careful reading of instructions
- Customer reviews indicate moderate satisfaction
Best for: Pool owners seeking a reliable, easy-to-install replacement for Hayward’s original CL200 feeder.
Not ideal for: Those with very large pools over 40,000 gallons or seeking a new system rather than a replacement part.
- Material:High-grade ABS
- Fits Pool Size:Up to 40,000 gallons
- Pipe Size:2-inch fittings
- Includes:2 O-Rings
Our verdict“This replacement is best for Hayward CL200 owners wanting a dependable, straightforward upgrade with precise control.”
U.S. Pool Supply In-Line Pool Automatic Chlorine Feeder, 9 lb
The U.S. Pool Supply Feeder caters to pool owners who prioritize straightforward operation and visibility. Its transparent lid allows quick monitoring of chlorine levels and remaining tablets, making it easier to maintain without guesswork. Its 9-pound capacity aligns with the Hayward CL200EF, but its simple dial control provides less precise dosing than models with electronic controls. Its durable ABS construction resists corrosion, but it requires manual refilling, which could be inconvenient for busy owners. Compared with the Hayward CL200EF, this feeder emphasizes ease of use over automation sophistication, making it suitable for those who prefer manual oversight but want a durable, easy-to-read device.
Pros:- Transparent lid for quick chlorine level checks
- Durable, corrosion-resistant ABS construction
- Simple dial control for adjusting flow
Cons:- Tablets not included, requiring manual refilling
- Less automation compared to electronic feeders
Best for: Pool owners seeking easy-to-monitor, manual refilling feeders with straightforward controls.
Not ideal for: Those wanting fully automated chlorine dosing or managing very large pools beyond 9 pounds capacity.
- Capacity:9 pounds
- Material:ABS Plastic
- Includes:Installation accessories, lid wrench, instruction guide
Our verdict“This feeder makes sense for owners who want a durable, easy-to-monitor system with manual control and straightforward operation.”
9Lbs In-Line Pool Chlorinator with 1.5″ Unions for Above Ground Pools
The 9Lbs In-Line Chlorinator excels for owners of large above-ground pools, especially those up to 40,000 gallons. Its 9-pound capacity and universal 1.5-inch fittings make it suitable for sizable pools needing substantial chlorine capacity. The dial control valve offers adjustable flow, similar to the Hayward and U.S. Pool Supply models, but its heavy-duty construction emphasizes durability for outdoor use. The device supports 3-inch tablets, which are not included, meaning extra purchase is necessary. While professional installation is recommended, this model provides a robust and straightforward solution for maintaining large pools. The main tradeoff is the need for manual refilling and the absence of included tablets, which some users might find inconvenient.
Pros:- Large capacity suitable for big pools
- Adjustable flow for precise chlorine control
- Heavy-duty, durable construction
- Universal fittings for easy replacement
Cons:- Chlorine tablets not included
- Professional installation recommended
- Manual refilling required
Best for: Owners of large above-ground pools seeking a durable, high-capacity chlorinator with adjustable flow.
Not ideal for: Pool owners with smaller pools or those preferring fully automated systems requiring minimal manual refilling.
- Capacity:9 lbs
- Pool Size Compatibility:Up to 40,000 gallons
- Fitting Size:1.5 inches
- Material:ABS plastic
- Maximum Pressure:50 PSI
Our verdict“This chlorinator is well-suited for large above-ground pools needing high capacity and adjustable flow, with the tradeoff of manual refilling.”
TOVEN-RV CL200 Inline Pool Chlorinator for Hayward CL200 and CL200EF
The TOVEN-RV CL200 stands out for its compatibility with popular Hayward models, making it a reliable choice for existing pool owners. Its adjustable chlorine feed allows precise regulation, which is a step above simpler fixed-flow models like the HydroTools 8750. The chemical-resistant reinforced ABS construction ensures durability, but it requires users to purchase unions and adapters separately, adding to installation complexity. Compared to the XtremepowerUS model, it offers better control but may involve a slightly more involved setup process. This makes it ideal for those who want flexibility and compatibility with their current systems but are comfortable with some additional accessories. The main tradeoff is that some installation parts are sold separately, which could increase initial costs.
Pros:- Adjustable chlorine feed for precise control
- Durable, chemical-resistant construction
- Easy to install in existing plumbing
Cons:- Unions and adapters not included, increasing initial setup cost
- Requires correct plumbing layout for fitment
Best for: Pool owners with Hayward CL200 or CL200EF systems seeking precise chlorine control and easy integration.
Not ideal for: Buyers without existing compatible plumbing or those seeking an all-in-one solution—since unions and adapters are sold separately and installation may require additional parts.
- Compatibility:Hayward CL200 and CL200EF
- Inlet/Outlet Thread Size:1-1/2 in inner, 2 in outer threads
- Material:Reinforced ABS
- Warranty:1 year
Our verdict“This pick is best for experienced pool owners who need flexible, compatible inline chlorination with precise dosage control.”
R171096 Compatible with Rainbow 320 Automatic In-Line Chlorine/Bromine Feeder for Pools and Spas
The R171096 offers a large capacity suitable for pools from 6,500 to 70,000 gallons, making it a flexible choice for larger bodies of water. Its upgraded sealing and control components enhance durability compared to older models like the Pentair Rainbow 320, which may experience leaks over time. While customer reviews cite some water leakage issues, the detailed instructions and included adapters make installation straightforward. It’s best for pool owners who want a cost-effective, wide-capacity chlorinator but are prepared for some maintenance and potential troubleshooting.
Pros:- Easy to install with detailed instructions
- Upgraded sealing and control components
- Suitable for a wide range of pool sizes
Cons:- Moderate average customer rating
- Some users report water leakage despite upgrades
Best for: Pool owners with large or variable-sized pools seeking easy installation and broad capacity.
Not ideal for: Those who prefer highly reliable, long-term solutions with minimal maintenance, as reviews indicate some leakage potential.
- Model Number:320
- Part Number:R171096
- Capacity:11 large or 98 small tablets
- Suitable Pool Size:6500 to 70000 gallons
- Application:In-line chlorinator for pools and spas
Our verdict“This model makes sense for owners needing a sizable, budget-friendly chlorinator with straightforward setup, accepting some possible maintenance.”
Pentair Rainbow 320 Automatic In-Line Chlorine/Bromine Feeder
The Pentair Rainbow 320 is designed for permanent in-line installation, offering durability and seamless integration for dedicated pool setups. It can hold both bromine and trichlor tablets, providing versatile chemical options. Unlike the R171096, it includes standard fittings and adapters for 2″ slip PVC, simplifying installation for those with existing plumbing. However, it does not include unions, which could complicate removal or maintenance. While it’s less flexible for portable setups, it excels in stability and long-term use. Compared to smaller, adjustable models like the HydroTools 8750, the Rainbow 320 prioritizes permanence and consistent chemical delivery, making it ideal for owners who want a set-it-and-forget-it solution but are willing to commit to a fixed installation.
Pros:- Easy to install with standard fittings
- Compatible with bromine and trichlor tablets
- Stable, permanent in-line setup
Cons:- Unions are not included, increasing installation complexity
- Limited flexibility for temporary setups
Best for: Pool owners seeking a durable, permanent inline chlorinator with broad chemical compatibility.
Not ideal for: Renters or owners who prefer portable or adjustable units, since this model is designed to be a fixed, long-term fixture.
- Capacity:Holds 11 large or 98 small bromine or trichlor tablets
- Installation:Permanent in-line
- Fittings:Includes 2″ slip PVC and adapters for 1-1/2″ unions
Our verdict“This feeder suits owners who want a durable, permanent solution with straightforward installation and broad chemical compatibility.”
HydroTools by Swimline 8750 Super Premium In-Line Automatic Chlorine Feeder
The HydroTools 8750 offers broad compatibility with both above-ground and inground pools, making it a versatile choice for many owners. Its adjustable chlorine output allows for tailored chemical dosing, which is a step up from fixed-dial models like the XtremepowerUS. The built-in solar-powered light adds aesthetic appeal, while the tilt indicator provides a simple way to monitor refilling needs. However, it can only hold five 3-inch tablets at a time, limiting its long-term capacity compared to larger models. Its universal design means it’s less optimized for specific pool sizes, and chlorine tablets are sold separately, adding to ongoing costs. It’s best for pool owners seeking flexibility and easy-to-use features without complex installation.
Pros:- Adjustable chlorine output for customization
- Solar-powered light adds ambiance
- Universal compatibility with various pool types
Cons:- Limited capacity at 5 tablets
- Chlorine tablets not included, adding to cost
Best for: Owners of above-ground or inground pools wanting adjustable chemical dosing and compatibility with different pool types.
Not ideal for: Large pool owners or those seeking high capacity, as it holds only five tablets, requiring frequent refills.
- Capacity:9.0 lbs
- Chlorine Tablet Size:3 inches
- Compatibility:Above ground & Inground pools
Our verdict“This feeder makes the most sense for owners who want adjustable, easy-to-maintain chlorination with aesthetic features, but with the tradeoff of needing frequent refills.”
XtremepowerUS Inline Automatic Chlorinator for Pools – Compatible with Cl200, 3-Inch Tablets
The XtremepowerUS inline chlorinator is a straightforward, budget-conscious option for small to medium pools. Its durable UV-resistant ABS body withstands outdoor conditions, and the adjustable dial control provides basic regulation of chlorine dispensing. Compared with the HydroTools 8750, it offers a simpler setup without additional features like solar lighting or universal compatibility, making it ideal for owners who prioritize affordability over bells and whistles. Its capacity of 9 lbs for 3-inch tablets makes it suitable for regular use but requires more frequent refilling in larger pools. The main tradeoff is that it doesn’t provide advanced control or aesthetic features, making it less suitable for owners seeking precise dosing or multi-functionality.
Pros:- Affordable price point
- UV-resistant durable construction
- Simple, easy installation
Cons:- Limited control over chlorine dosing
- Requires frequent refilling for larger pools
Best for: Budget-conscious owners with small or medium-sized pools looking for a reliable inline chlorinator without extra features.
Not ideal for: Owners with large pools or those wanting adjustable output or aesthetic features like solar lighting, as this model is basic and limited in capacity.
- Material:UV-resistant ABS
- Tank Capacity:9 lbs
- Compatible Tablets:3-inch
Our verdict“This model is best for small to medium pools where affordability and simplicity are key, accepting less control and capacity.”
Hayward CL100 Automatic Chlorine Feeder
The Hayward CL100 stands out as the most reliable choice for above-ground pools, thanks to its corrosion-proof plastic construction that withstands outdoor elements better than some metal-based alternatives. Its easy-to-use dial control allows for straightforward adjustment of chlorine feed rates, making it accessible for DIY pool maintenance. Compared with the Hydrotools model, the CL100 is simpler, lacking digital features but offering a more durable, lightweight build suitable for straightforward setups. The main tradeoff lies in its limited to above-ground pools, which makes it less versatile for inground systems. Its small weight suggests a lightweight design, which may raise concerns about robustness over time. Overall, this feeder makes sense for pool owners seeking reliable, easy installation without extra bells and whistles.
Pros:- Corrosion-proof plastic construction for outdoor durability
- Simple, intuitive dial control for easy adjustments
- Lightweight and easy to install
Cons:- Limited to above-ground pools, reducing versatility
- No digital or advanced control features

Not ideal for: Inground pool owners needing a more robust, feature-rich system with digital controls.
- Power Source:AC, AC/DC
- Flow Rate:50 gpm
- Material Type:Plastic
- Style:Color Black
- Product Style:Above Ground
- Item Dimensions:16″L x 8″W x 8″H
Our verdict“This model is perfect for above-ground pool owners seeking a straightforward, durable chlorine feeder.”
Hydrotools by Swimline 87502 Premium In-Line Automatic Chlorine Feeder, 9.0 Lb Capacity, Universal Compatibility
The Hydrotools 87502 is a solid choice for pool owners who want flexibility, thanks to its adjustable 360° dial that makes it easy to fine-tune chlorine or bromine dispensing. Unlike the Poolzilla model, which is more straightforward, Hydrotools offers a more precise control suited for pools with varying chemical demands. Its corrosion-resistant thermoplastic construction ensures longevity, but it does not support simultaneous chlorine and bromine use—an important consideration for owners wanting chemical mixing options. Its 9 Lb capacity can be limiting for larger pools or high-use situations, requiring more frequent refilling. Overall, this feeder is well-suited for users with existing pool systems who value adjustable, reliable dosing over capacity or digital features.
Pros:- Adjustable 360° dial for precise chemical dosing
- Durable, corrosion-resistant thermoplastic build
- Universal 2-inch inlet and outlet for broad compatibility
Cons:- Cannot mix chlorine and bromine simultaneously
- Limited to 9 Lb capacity, requiring frequent refills for large pools
Best for: Pool owners with moderate to large pools seeking adjustable, compatible chemical dispensing.
Not ideal for: Owners who prefer digital controls or need to mix chemicals simultaneously, as it only supports one type at a time.
- Capacity:9 Lbs
- Inlet & Outlet Connection:2 Inch
- Compatible with:Chlorine & Bromine (do not mix)
- Material:Thermoplastic
- Application:Above ground & inground pools
Our verdict“Ideal for pool owners wanting adjustable chlorine or bromine delivery with broad system compatibility.”
Poolzilla Automatic Chlorinator – In-line Chlorine Feeder – 9lb Tank
The Poolzilla Automatic Chlorinator is designed for those who prioritize ease of installation and durability. Its corrosion-proof construction makes it a dependable option for both above-ground and inground pools, especially for users with standard PVC piping setups. Compared with Hydrotools, the Poolzilla offers a slightly more flexible fit, accommodating both 1-inch and 3-inch tablets, which broadens compatibility with different tablet types. Its adjustable dial control allows for simple feed rate management, but its 9-pound capacity can be limiting for larger or heavily used pools, requiring more frequent refills. This model is best suited for pool owners who want straightforward operation and reliable, corrosion-proof materials without extra digital features.
Pros:- Corrosion-proof design for long-term durability
- Compatible with 3-inch and 1-inch tablets for flexibility
- Easy to install and adjust with dial control
Cons:- Limited to 9 lbs tablet capacity, requiring frequent refills

- Compatible with:Standard PVC piping
Our verdict“This feeder is best for pool owners who value durability, simplicity, and compatibility with various tablet sizes.”
How We Picked
To determine the best pool inline chlorinators, I evaluated each product based on performance, ease of installation, durability, compatibility with various pool types, and overall value. I focused on models that have proven reliability in real-world use, including their ability to regulate chlorine levels accurately. The ranking also considers customer reviews and brand reputation to account for long-term satisfaction. Products were compared on their features versus price, ensuring that each pick offers a clear benefit for specific types of pool owners, from beginners to experienced users.Factors to Consider When Choosing Pool Inline Chlorinator
Choosing the right pool inline chlorinator involves understanding several key factors that impact performance, ease of use, and long-term maintenance. While price is important, focusing on compatibility with your pool size and type, ease of installation, and control features will help you make a smarter investment. The right chlorinator should seamlessly integrate into your pool’s plumbing and provide reliable, consistent sanitation over time.Pool Size and Capacity
Matching a chlorinator’s capacity to your pool size is critical. Larger pools require units with higher chlorine output and larger tanks to reduce refilling frequency. Choosing an undersized model can lead to inconsistent chlorination, while an oversized unit might be unnecessary and cost more upfront. Always check the product’s recommended pool volume to ensure compatibility and optimal performance.
Compatibility and Installation
Some chlorinators are designed for specific pool types, such as above ground or in-ground pools, or particular plumbing sizes. Proper installation is key to avoiding leaks and ensuring even chlorine distribution. Look for models with flexible fittings or universal designs if you have a non-standard setup. Avoid units that require complex modifications unless you’re comfortable with plumbing work.
Ease of Use and Adjustment
Ease of control varies widely among models. Features like adjustable chlorine output, clear dosing indicators, and built-in timers make maintenance straightforward. In contrast, basic models may require manual adjustments with less precision, leading to potential over- or under-chlorination. Consider how much effort you’re willing to invest in daily or weekly adjustments when selecting a model.
Durability and Maintenance
Materials used in construction influence longevity, especially in harsh pool environments. Corrosion-resistant plastics and sealed chambers help prevent damage from chlorine and water exposure. Regular cleaning and inspecting for leaks are necessary to keep the unit functioning well. Investing in a durable model might cost more initially but pays off through fewer repairs and replacements.
Cost and Long-Term Value
While budget models are tempting, they often lack features that improve reliability or convenience. Conversely, premium options may include advanced controls and higher durability, which can justify a higher price for larger or more demanding pools. Consider your long-term needs and how much you’re willing to spend upfront versus potential savings on maintenance and refills over time.
Frequently Asked Questions
How often should I refill my inline chlorinator?
The refill frequency depends on your pool size, usage, and the chlorinator’s capacity. Typically, smaller units need refilling every 1-2 weeks, while larger tanks may last longer. Regularly check the chlorine levels and the tank’s weight to avoid running out unexpectedly. Properly maintained units with adjustable output can help you fine-tune refilling schedules for consistent sanitation.
Can I use any type of chlorine tablets in an inline chlorinator?
Most inline chlorinators are compatible with standard trichlor tablets, but it’s important to verify the size and chemical composition recommended by the manufacturer. Using incorrect tablet sizes or types can cause blockages or uneven dosing. Some models are compatible with bromine tablets as well, providing flexibility for different sanitization needs.
Is an inline chlorinator suitable for saltwater pools?
Inline chlorinators are primarily designed for use with chlorine tablets and are not suitable for saltwater pools, which generate chlorine via salt electrolysis. For saltwater systems, a dedicated salt chlorine generator is recommended. Using a chlorinator intended for traditional chlorine tablets in a saltwater pool can cause corrosion and damage to the unit.
What maintenance does an inline chlorinator require?
Routine maintenance includes cleaning the chlorinator chamber to prevent buildup of mineral deposits, inspecting for leaks, and checking the chlorine levels regularly. Some units have removable parts that should be rinsed or replaced periodically. Ensuring compatibility with your pool chemistry and performing regular inspections will prolong the lifespan of the device.
When should I upgrade my inline chlorinator?
If your current unit frequently leaks, clogs, or requires constant manual adjustments, it may be time to upgrade. Additionally, if your pool has grown larger or you want more precise control over chlorine dosing, newer models with advanced features will better meet your needs. Investing in a higher-quality, durable unit can reduce ongoing maintenance and improve overall pool water quality.
Conclusion
For most pool owners, the Hayward CL200EF offers the best combination of reliability and ease of use, making it ideal for those seeking an all-around solid performer. Budget-conscious buyers should consider the HydroTools 8750 for dependable basic functionality without extra bells and whistles. If you’re looking for a premium option with advanced controls, the Pentair Rainbow 320 provides excellent precision and durability. Beginners or those with smaller pools will find simpler models like the Hayward CL100 easier to manage, while larger pools benefit from high-capacity units like the Poolzilla 9lb. Ultimately, your choice hinges on pool size, budget, and desired features.
