Buying Guide

When selecting an automatic bromine dispenser for a hot tub, consider the following factors:

  • Tablet size compatibility: Most spa floaters use 1″ tablets, but some models accommodate 1.5″ or larger. Choose based on the tablets you plan to use and the dispenser’s capacity.
  • Flow control range: Look for 6 to 13 adjustable settings. More settings provide finer control over chlorine or bromine release, helping maintain stable water balance across varying demand.
  • Durability and materials: Durable ABS or PVC housings resist corrosion and UV exposure. A weighted or screw-on cap improves stability in active spa environments.
  • Ease of loading and refilling: A twist-lock cap or simple screw cap speeds loading while minimizing tablet exposure to air, which can impact dissolution.
  • Compatibility with bromine vs chlorine: Some floaters are designed for either chemical, while others support both. Ensure the unit aligns with your preferred sanitizer system.
  • Size and target area: Larger tubs may benefit from bigger dispensers or those with 13+ flow settings; smaller spas may prefer compact designs with precise dosing.
  • Maintenance needs: Choose models with clear indicators or refill alerts, such as pop-up indicators or color cues, to simplify upkeep.
  • Safety: Ensure the dispenser is stable, floats correctly, and minimizes direct contact with concentrated chemicals.

For best results, pair a compatible bromine-based sanitizer with a dispenser that offers consistent, adjustable release. Regular water testing remains essential to verify circulating water maintains the target bromine level and total alkalinity stays within range.
