And Disinfectant in Swimming Pools and Spas | Slow Dissolving and UV Protected, Algaecide, Rx Clear 3-Inch Individually Wrapped Chlorine Tablets | One 25-Pound Bucket | Use As Bactericide

#ad
Rx Clear #ad - Long lasting - these rx clear chlorine tabs are slow dissolving, 90% available chlorine, 99% Trichlor. Trust rx clear to balance your pool and spa chemistry and keep your water safe and clear. Easy to use - each individually wrapped chlorinating tablet weighs 7 ounces.

Adaptable to your pool or hot tub - use 2 tablets per 10, 000 gallons of pool water as needed by adding the pool chlorine tablets to your existing inline/offline chlorinator and using the flow of your pump to dissolve and distribute the pool chemicals or to a floating chlorine dispenser. This breakage is normal and does not reduce the effectiveness of these tabs.

Low price, high quality - compared to other brands, the Rx Clear brand provides more available chlorine in each tab at a much lower cost. Note: some of the tablets may be cracked or broken within their packaging due to shipping. Trusted pool supplies - rx clear has high quality pool chemicals and pool accessories for a great value.
