Buying Guide: Inline Chlorinators For Above Ground Pools
- Capacity and refill frequency: If you have a larger pool, prioritize 9 lb capacity to reduce refills. For smaller setups, a 4.2 lb or similar model may suffice.
- Compatibility: Verify that the feeder matches your pool’s brand or system (for example, CL200, CL100, or universal designs). Check threading and inlet/outlet sizes.
- Materials and durability: Look for corrosion-resistant housings and ABS plastic bodies to withstand pool chemicals and UV exposure.
- Ease of installation: Consider models with simple lid seals, clear adjustment dials, and included installation accessories like lid wrenches.
- Control and dosing: Adjustable output control is important for tailoring chlorine delivery to pool size, usage, and weather conditions.
- Tablets compatibility: Confirm whether the feeder accepts 3-inch or 9-pound tablets, and if tablets or sticks are included with the unit.
- Safety and maintenance: Favor units with leak-proof lids and easy access for safe tablet addition. Periodic lubrication of O-rings may extend life.
- Pool type: Above-ground pools often require different fittings than in-ground setups. Ensure the feeder is rated for your pool type and is easy to install with existing equipment.
