10 Best Floating Chlorine Dispensers 2025 in the United States

The Floating Chlorine Dispenser from Merkia is a notable choice for maintaining clean and sanitized water in your pool or spa. It is designed to float and evenly distribute chlorine throughout your pool, which ensures effective sanitation. Made from durable ABS plastic, this dispenser promises long-lasting use, potentially saving you money in the long run.

With a large capacity, it can hold up to four 3-inch chlorine or bromine tablets, making it efficient for less frequent refills. The adjustable control ring is a great feature, allowing you to control the release rate of the chemicals for a balanced chlorine delivery. This makes it versatile for various pool sizes and types, including above-ground and in-ground pools, spas, water parks, and even aquariums.

One of its standout aspects is its ease of use; simply load the tablets and set it afloat. However, the device is relatively large, which might not be suitable for smaller pools or spas. Additionally, some users may experience issues with maintaining the desired chlorine level, depending on their specific pool conditions. This product's top ranking in Pool & Spa Parts & Accessories reflects its popularity and reliability.

The Floating Mini Spa Chemical Dispenser is designed for smaller bodies of water like spas, hot tubs, fountains, and smaller pools. One of its main strengths is its adjustable release rate, which allows you to control how much chlorine is dispersed into the water, ensuring optimal water quality. Additionally, its durable ABS plastic construction promises longevity, making it a reliable choice for years to come. With a capacity for 1-inch chlorine or bromine tablets, it suits smaller maintenance needs effectively.

The dispenser's size (5.5 x 5 x 5 inches) makes it compact and buoyant, ensuring it can float around and reach all areas of your pool or spa. It's also user-friendly: just fill it with tablets, twist the locking cap, adjust the settings, and let it float. This ease of use is great for those who want straightforward pool maintenance without much hassle.

However, since it's designed for 1-inch tablets and smaller volumes, it might not be suitable for larger pools or situations needing more substantial chlorine quantities. Some users might also find the twist-lock cap less secure over time. Despite these minor drawbacks, it is widely trusted and effective for the appropriate pool sizes and uses.

The U.S. Pool Supply Floating Chlorine and Bromine Dispenser is designed mainly for spas, hot tubs, and small pools, making it a great fit if you want to keep chemical levels balanced without frequent refills. 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. One of its strengths is the weighted, flat-top design which helps it stay in place, even under solar covers, and prevents it from getting stuck in filters. This means less hassle and better chemical distribution. The dispenser is made from heavy-duty materials, so it’s fairly durable and can last through cold winter months without needing constant attention.

Its capacity is suited specifically for smaller pools or spas, so it might not be ideal if you have a large backyard pool. While the 13 flow settings offer flexibility, some users might find fine-tuning a bit tricky at first if they’re new to chemical dispensers. 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.
