Features

  • Professional Grade: Heavy-duty weighted floating spa, hot tub, and small pool chlorine and bromine chemical dispenser. It holds 1" chlorine or bromine tablets.
  • 13 Control Settings: The 13 adjustable chemical flow control settings make it easy to set the dispenser for worry-free balanced chemical release.
  • 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.
  • Flat Top Weighted Dispenser: The dispenser's flat top allows it to lay flat under solar covers, and the weighted screw on bottom cap prevents the dispenser from getting caught in the spa or hot tub filter.
  • Buy with Confidence: Backed by a trusted brand dedicated to your satisfaction, we ensure a hassle-free experience every time

Works very well, very sturdy, easy to fill. I use mine in our hot tub and I didn’t like it floating into me if the jets were on or it was a windy day so I just got a yard of twine, looped it over the top of this dispenser and secured the ends of the twine under the hot tub cover. Problem solved.

    • U.S. Pool Supply Floating Spa, Hot Tub & Small Pool Chlorine Dispenser - 1" Tablet
Size: 13-Flow
I really like this chlorine dispenser. It is slimmer than my original one (which lasted 25+ years), but is better made and made of a thicker and heavier plastic, plus the round floating part is flatter and better sealed. It looks like it will last longer than my original dispenser. A year ago, I bought a floating dispenser from Home Depot as a replacement, it was make of thin plastic and became very brittle and broke apart within a year. Get this float, you won't be sorry...besides, it is much prettier. I used to use the thicker 1" chloride tablets for my floater, but Home Depot no longer carry them, so I got some flat 1" tablets from Amazon and it turn out that they did a much job at dispensing the chlorine and keeping the green algae at bay. UPDATE: It is now Jan 2023, the float is sturdy as ever. The gray top is lighter in color, but the submerged blue part is still very blue. ... show more

    • Solves chlorine level headache
Size: 13-Flow
It made my chlorine level consistent instead of fluctuating up and down all the time. Very easy to use.

    • OK after 2 years.
Size: 13-Flow
Have had this for 2 years. It’s not pristine but does the trick. However the cap on the bottom got so stiff almost immediately that we have to unscrew the whole thing to add tablets which is a pain. Some of the threads have discolored and broken off a bit but doesn’t affect the function. It’s a cost effective and easy way for us to keep our hot tub clean. ... show more

    • A great product for a pool or spa!
Size: 13-Flow
Overall, it's a great functional design. The plastic seems to be more superior than other brands I have bought in the past. The price point also fit my budget.

Works perfectly in my Hot Tub so I don’t have to refill the bromine often . If you’re going on, vacation allows you to control the amount of chemicals going into your hot tub by adjusting the device.

    • Durable Chlorine Tab Dispenser
Size: 13-Flow
This has been my go to chlorine tab float for our hot tub. Like everything chlorine touches, the dispenser eventually degrades but I think we get a bit longer life than we’ve gotten with some of the other models. This float replaces one that was at least two years old.

Bought this product last year and it works great , especially if traveling can adjust level of dispensing. However the chlorine tab weakened the plastic and it broke. Had to replace this year with new unit
