Professional Grade: Heavy-duty weighted floating spa, hot tub, and small pool chlorine and bromine chemical dispenser. It holds 1" chlorine or bromine tablets. Includes tie string. 6 Control Settings: The 6 adjustable chemical flow control settings make it easy to set the dispenser for worry-free balanced chemical delivery. Just twist the top to set delivery from 1 to 6. Longer Time Between Refills: Fill it completely, so you can set it and almost forget it. Just a simple turn adjusts it for more chemical delivery. Great for cold winter water, as it can last for months. When the dispenser is fully filled with tablets, the red piece in the middle of the dispenser top will stay all the way up and gradually go down, alerting you when the dispenser is empty.
