desertcart.com : U.S. Pool Supply Spa, Hot Tub, Small Pool, 4-1/2" Diameter Floating Chlorine & Bromine Chemical Dispenser with 120° F Thermometer, Holds 1" or 1-1/2" Tablets - Adjustable Chemical Delivery : Patio, Lawn & Garden

Review: Large Pool Floating Chlorine Chemical Dispenser - This Large Pool Floating Chlorine Chemical Dispenser is such a great addition to our small pool. The bottom of the dispenser holds 3 chlorine tablets. The Dispenser has slits that you can turn to allow more or less of the amount of Chlorine that you need. Another nice feature is the 120°F thermometer. For me, that determines if the pool is a good temperature for me to use the pool. This Dispenser is very durable. It floats around the pool and is easy to grab when taking it out of the pool. When using the Chlorine tablets it keeps the pool clean. I would highly recommend this product.
Review: Accurate and just right - Bought at end of May. The thermometer is accurate compared to hot tub's temperature display. I like the squaty profile of this. It DOESN'T hang down it the water too much and bump into your legs. I also like that you load the bromine tablets into the TOP. The previous one we had was a bottom load and that one opened up.
