ADORABLE WAY TO CHLORINATE YOUR POOL: The GAME Derby Duck Pool Chlorinator is an adorable way to keep your inground or above-ground pool properly chlorinated. It holds up to five 3-inch chlorine tablets (not included). EASY TO USE: This adjustable floating pool dispenser comes with an expandable basket that can accommodate a number of 3-inch chlorine tabs. Users can adjust the basket to the size of their pool for correct chlorine distribution. PERFECT FOR ABOVE OR INGROUND CHLORINE POOLS: Our chlorine basket can be purchased as our Derby Duck, a cute clownfish, or a shark. It’s perfect for above-ground or inground chlorine pools of multiple sizes. TIPS OVER WHEN EMPTY: The GAME chlorine duck floater tilts or tips over once all of the chlorine tablets have dissolved or it needs to be refilled. ADJUSTABLE CHEMICAL-DISPENSING RATE: To ensure your chlorine swimming pool receives the right amount of chlorine, we’ve installed an adjustable chemical-dispensing rate (determined by the size of the pool).
