Adjustable 3" Chlorine Tablet Floater – 4 lb Dispenser CL290ABW
Simplify Pool Sanitization with Adjustable Chlorine Control
Keep your pool sparkling clean with the Adjustable 3" Chlorine Tablet Floater (CL290ABW)—a large-capacity 4 lb chlorine dispenser designed for both residential and commercial pools. This heavy-duty floater automatically releases chlorine into your water, maintaining balanced sanitizer levels and reducing the need for daily dosing.
With its adjustable flow control and secure locking lid, the CL290ABW offers safe, consistent, and customizable chlorination for any pool or spa. Whether you use standard 3" chlorine tablets or slow-dissolving sanitizers, this durable dispenser keeps your water crystal clear all season long.
Designed for Safe and Efficient Chlorine Delivery
The CL290ABW tablet floater uses a precision-adjustable vent system that lets you control how quickly chlorine dissolves and disperses into your pool. Simply rotate the bottom collar to increase or decrease flow based on your pool’s size and usage.
This ensures steady chlorine levels without over-chlorination, which can cause irritation, or under-chlorination, which can lead to cloudy water and algae growth.
With the CL290ABW, maintaining your pool’s sanitizer balance is as simple as turning a dial.
Large 4 lb Capacity for Extended Cleaning Cycles
Unlike small, single-tablet floaters, the CL290ABW holds up to 4 pounds of chlorine tablets—enough to sanitize most pools for days or even weeks, depending on temperature and usage.
The extra capacity means fewer refills and more consistent chlorination over time, especially during hot weather or high-traffic periods when sanitizer demand is highest.
Just fill, adjust, and let it float—no electrical power, pumps, or automation required.
Safe, Secure, and Built to Last
Durability and safety are top priorities in pool maintenance, and the CL290ABW delivers both. Its chemical-resistant ABS construction resists fading, cracking, and chemical wear caused by constant exposure to UV light and chlorine.
The locking twist-on lid prevents accidental spills and keeps chlorine tablets safely contained, even if the floater tips or bumps against the pool wall.
It’s designed for peace of mind—safe for use in pools, spas, and even fountains.
Easy to Use and Adjust
Operating the CL290ABW Adjustable Chlorine Dispenser is quick and straightforward:
-
Open the locking lid and add up to 4 lbs of 3" chlorine tablets.
-
Twist the adjustable collar at the base to set the desired flow rate.
-
Place the floater in the pool, away from walls and steps.
-
Check weekly and adjust flow as needed based on chlorine test results.
The wide-mouth design makes loading tablets fast and mess-free, while the adjustable vent ensures precision dosing every time.
Maintains Consistent Sanitization Levels
Proper chlorine control prevents algae, bacteria, and other contaminants from taking hold in your pool. The CL290ABW helps maintain ideal sanitizer levels between 1.0–3.0 ppm, keeping water clean, clear, and safe for swimmers.
Whether you’re managing a backyard pool, hotel pool, or spa, this floating dispenser provides professional-level control without automation or electricity.
Ideal for Pools, Spas, and Fountains
This versatile chlorine floater works in a variety of water environments, including:
-
Residential swimming pools
-
Commercial pools or resorts
-
Spas and hot tubs (with smaller tablets)
-
Decorative fountains and ponds
It’s also compatible with most types of sanitizers, including chlorine tablets, bromine tabs, and slow-dissolving chlorine sticks, giving you flexibility for any water system.
Built for Longevity and Stability
The weighted base keeps the CL290ABW upright while floating, preventing it from tipping or drifting into skimmers or steps. The UV-protected construction maintains color and strength even under direct sunlight, ensuring long-term reliability through multiple pool seasons.
