Sunken Treasure Original Sinking & Floating Pool Chlorine Dispenser – Sinks, Cleans, Floats Up

Meet Sunken Treasure, the original chlorine dispenser that sinks, cleans, and then floats back up for easy refills. By keeping the chlorine tablet submerged, it treats pool water from the bottom up, where it matters most, and minimizes the loss of chlorine to the air.

When deployed, the unit holds a standard chlorine tablet deep underwater, releasing sanitizer directly into the water. As the tablet finishes, the dispenser rises to the surface for a simple refill, turning pool maintenance into a straightforward routine.

Why choose Sunken Treasure

Traditional floating dispensers often waste chlorine as tabs evaporate or drift away with sunlight. The Sunken Treasure uses far less chlorine while delivering consistent dosing, helping you maintain clear water and a more inviting pool feel. The experience includes a lighter chlorine scent and healthier looking water that remains blue and vibrant after several days of swimming.

• Lower chlorine usage: a single tablet in the Sunken Treasure can equal multiple tabs in a floater, depending on pool size.
• Bottom up treatment: the tabs dissolve where the water is deepest, supporting even distribution.
• Durable design: built to withstand sun exposure and years of use, saving you money over time.
• Better pool experience: less air fragrance of chlorine and clearer, sparkling water for guests and family.

How many units you might need

Choose the number of units based on your pool size and layout. For many standard pools up to 12,000 gallons, one unit works well. Larger pools may benefit from two units, and very large pools over 25,000 gallons can use three units for balanced coverage. The dispenser is compatible with pools and spas in various climates and environments.

• 1 unit for typical pools up to 12k gallons
• 2 units for pools over 15k gallons
• 3 units for very large pools over 25k gallons

Notes and care

Made in the USA, the Sunken Treasure emphasizes durability and value, designed to endure underwater and resist wear. It is not recommended for dark plaster pools or vinyl lined pools, where chlorine exposure may cause premature bleaching. With proper use, many pool owners find a more pleasant water experience and less routine fuss during the season.
