Buying Guide
- Tablet compatibility: Ensure the dispenser supports the tablet sizes you use (1″ and/or 3″ are common).
- Capacity: A larger capacity means fewer refills; check how many tablets the unit can hold and whether that meets your pool size and usage.
- Flow control: Look for an adjustable release or flow ring to tailor chlorine delivery to pool volume, splash-out, and weather changes.
- Durability: Materials like ABS plastic and UV-resistant components extend life in sun-exposed outdoor environments.
- Maintenance: Consider ease of cleaning, secure lids, and whether the device collapses for storage when not in use.
- Pool type compatibility: Confirm whether the dispenser works with inground, above-ground, hot tubs, or spas, depending on your setup.
- Safety and placement: Floating dispensers sit on the surface; ensure they won’t obstruct skimmers, ladders, or pool toys.
- Replacement parts and warranty: Check availability of replacement parts and any included manufacturer warranty for long-term value.
