U.S. Pool Supply Floating Spa & Hot Tub Chlorine/Bromine Dispenser – 13-Setting Adjustable Dial, Weighted Bottom

This compact chemical dispenser is built to deliver controlled amounts of chlorine or bromine tablets to spas, hot tubs and small pools without constant monitoring. Designed with a flat top to fit beneath solar covers and a weighted bottom cap that resists filter suction, the unit helps maintain sanitizer levels for weeks or even months depending on usage and setting. Constructed for frequent use and easy adjustment, it suits seasonal storage and winter setups as well.

How does this dispenser regulate sanitizer levels?

The dispenser uses a 13-position adjustable dial that varies the opening size to control tablet exposure and the resulting chemical release. Turning the dial increases or decreases the flow, giving you granular control over sanitizer delivery without removing the tablet. Because the interior accepts standard 1" chlorine or bromine tablets, it works with common pool chemicals for easy refills.

• 13 adjustable flow settings to fine-tune release speed
• Fits standard 1" chlorine or bromine tablets for easy sourcing
• Simple twist adjustment—no tools required

Will it stay put under covers and near filters?

Yes — the dispenser is weighted at the bottom and features a screw-on cap that prevents it from being pulled into skimmers or sucked against filters. The flat top profile lets it sit flush under solar blankets and cover edges, reducing the chance of it getting pinched or trapped. Its low center of gravity keeps it stable in light currents common to small pools and hot tubs.

• Weighted bottom cap prevents filter suction issues
• Flat top design fits under solar covers without bulging
• Stable flotation resists light surface currents

How often will I need to refill or adjust it?

Refill frequency depends on water temperature, bather load and chosen dial setting; cooler water and lower settings extend tablet life. When used in cold winter water or on conservative settings, a full load can last multiple weeks to months. Higher temperatures and heavy use require more frequent checks and refills.

• Cold-water use and low settings: longest tablet life
• Warm water and heavy use: increases refill frequency
• Easy to check—open cap, swap tablet, and re-set the dial

Is this unit durable and easy to use?

Built for routine pool and spa maintenance, the dispenser is made from heavy-duty materials to resist cracking and wear from chemical exposure. The screw-on bottom cap and twist adjustable top simplify tablet replacement and flow adjustment. U.S. Pool Supply backs the product for customer satisfaction, which helps if you need support or replacement guidance.
