It holds 1-inch chlorine or bromine tablets and features 13 different flow settings, so you can easily control how quickly the chemicals dissolve based on your water temperature and pool size.

Weighing just 8 ounces and sized compactly, it floats well without tipping over easily, which is important for safe and steady chemical release. For those looking for an easy-to-use, reliable dispenser to maintain water cleanliness in a small pool or spa, this model provides a solid balance of convenience and performance.
