In & Above Ground Swimming Pool Chemical Feeders

Automate your pool's sanitization with a pool chemical feeder that delivers consistent chlorine or bromine dosing without daily manual additions. PST Pool Supplies stocks automatic chlorinators, liquid chemical dispensing systems, and smart pH/ORP dosing platforms for both in-ground and above-ground pools — from brands including Hayward, Pentair, CMP, Rainbow, and Blue-White Industries, with prices starting from $124.

The Hayward chlorinator lineup covers the most common residential feeder needs: the CL200 inline chlorinator and CL2002S 2" inline model fit directly into the return plumbing after the filter; the CL220ABG offline chlorinator is designed for above-ground pool installations with a simple bypass connection. The Hayward brominator (CL220BR) mirrors this design for bromine tablet systems. For full chemical automation, the Pentair IntelliChem (models 522577 and 522578) is an industrial-grade chemical controller that continuously monitors pH and ORP and automatically doses acid and liquid chlorine to maintain target levels — compatible with Pentair's IntelliConnect and EasyTouch automation platforms. The CMP PowerClean Ultra is a high-capacity in-line chlorinator with a clear glass lid for easy monitoring. For precise liquid chemical metering, Blue-White FlexFlo peristaltic pumps deliver accurate, repeatable dosing for liquid chlorine, acid, or algaecide injection systems. For full system integration, see our pool automation systems collection. Pentair IntelliChem documentation is available at Pentair's official support site.

When selecting a pool chemical feeder, match the feeder type to your plumbing configuration. Inline chlorinators require cutting into the return line — they offer the most reliable, consistent dosing and are recommended for all permanent in-ground installations. Offline feeders use a bypass loop and are easier to retrofit, particularly on above-ground pools with flexible plumbing. Liquid chemical systems (IntelliChem, FlexFlo) are best suited for pools requiring precise pH management or those already running liquid chlorine programs. Always install chemical feeders on the return line after the heater and other equipment to prevent chemical corrosion of upstream components. See our automation parts collection for sensors and relay components compatible with chemical dosing systems.

Shop pool chemical feeders and take the guesswork — and daily chore — out of pool sanitization.
