The Hayward CL100 Automatic Chlorine Feeder is a no-fuss solution for above-ground pool owners who want to automate their sanitizer delivery. It uses standard 3-inch trichlor tablets and works seamlessly with your existing pump and filter system, making it a practical upgrade for anyone tired of manual dosing.

Standout features include a dial control valve that lets you fine-tune the chlorine feed rate, and a durable plastic body that resists corrosion from pool chemicals. Real-world users report that a single load of tablets can last up to three weeks, significantly reducing maintenance frequency. The unit installs easily with standard PVC connections, and many reviewers have praised its longevity, with some units lasting over 20 years.

Build quality is solid for a plastic chlorinator. The Easy-Lok threaded cover and finger-release catch provide a secure seal, preventing accidental openings and minimizing gas escape. The unit is lightweight at just 4 ounces, but its construction feels robust enough for typical above-ground pool use.

A critical drawback is the safety hazard when opening the feeder. The concentrated chlorine gas that builds up inside can be dangerous, as highlighted by multiple user reviews. Always wear goggles and a high-quality respirator mask before opening, and work in a well-ventilated area. Additionally, the plastic threads require careful use of Teflon tape to prevent leaks.

Overall, the Hayward CL100 is a top choice for above-ground pool owners who value reliability, ease of use, and cost savings. Its automatic operation and long-lasting build make it a worthwhile investment, provided you follow safety precautions. For a straightforward, effective chlorinator, this model is hard to beat.

This chlorinator can accumulate dangerous chlorine gas inside the unit when closed. Opening the lid releases this gas, which can cause severe respiratory irritation, poisoning, or eye damage. Always wear chemical-resistant goggles and a high-quality mask with filters (e.g., a welding respirator) before opening. Do not rely on simple safety glasses. Open the lid slowly and stand upwind to avoid inhaling fumes. If you feel sick after opening, seek fresh air immediately and consult a doctor. Never open the unit indoors or in an enclosed space.

Build quality is solid with a chemical-resistant PVC liquid end, though the pump is notably louder than some competitors. The universal voltage motor supports both 115V and 230V, giving flexibility for different electrical setups. The included instructions are clear, but some users have noted that the tubing compression fittings may need extra washers to prevent leaks.

For well owners seeking an affordable, reliable chlorinator, the PF30 delivers strong performance at a fraction of the cost of name-brand models. The noise is a trade-off, but it does not affect functionality. The pump is straightforward to wire and install, and parts are available online.

The Waterway Plastics CAG004-W Clearwater in-line automatic chlorinator is a practical chemical feeder designed specifically for above ground pools. It is an excellent choice for pool owners who want to maintain consistent sanitizer levels without daily manual dosing.

This chlorinator works by connecting directly into the pool's return line, allowing water to pass through a chamber filled with chlorine tablets. As water flows, it dissolves the tablets and distributes chlorine evenly throughout the pool. This reduces the need for frequent chemical handling and helps keep algae and bacteria at bay.

Manufactured by Waterway Plastics in the USA, the unit features a clear housing that lets you see when the chlorine tablets are running low. The compact, lightweight design makes it easy to install and fit into most above ground pool plumbing setups. The plastic construction is durable enough for outdoor use, though it is not meant to withstand heavy impact.

One potential drawback is that the clear housing may become cloudy over time, making it harder to view the tablet level. Some users have also reported that the fittings may require adapters to match certain pool hoses, so checking compatibility before purchasing is recommended. Regular cleaning of the chamber can prevent debris buildup and maintain flow.

Overall, the Waterway CAG004-W is a reliable and straightforward solution for automating chlorine delivery in an above ground pool. It offers good value for pool owners seeking a no-fuss chlorinator that does the job without complicating the system.

It connects to your existing pump and filter system, dissolves 3-inch tablets as water flows through, and is equally suited to above-ground and inground pools.
