Rx Clear 1" Inch Stabilized Chlorine Tablets | 8 Lbs | Use Tabs as Bactericide, Algaecide, & Disinfectant in Swimming Pools | Long Lasting, Slow Dissolving, & UV Protected

Works awesome for the hot tub levels are good

This is the best tab I have ever used in my hot tub which is now 17 years old. Long lasting as compared to the other tabs I have used. Also, they are the best value per tablet used. Each one-inch tab lasts about 3 days in my 350-gallon tub. Also, I add shock about once a month.

Use 3 of these in my water fountain and it keeps the water perfectly clear. Appears to leave a residue of purple around the edges and not sure why?

I felt the available chlorine was a bit low, normally i use 4 3 Inch pucks, but these were a bit cheaper so I gave them a shot, and it wasn't really worth it. I'm sure a smaller or above ground would be fine with them.

I needed 1" tablets for my small dispenser in my pond. These were well priced, and it's nice that, inside the tub, there are actually multiple bags of tablets. So you can open up one pound at a time, and the rest stay nicely packaged in bags, safer from water splashing. My pond is clean, so I guess the chemical makeup is good as well.

Cheapest and best value

Kept in a climate controlled environment and used for a hot tub these have remained solid and viable for 18 Months

Got these for two large outdoor fountains. The size of the tablets are as shown not wafer size. The value was wonderful compared to Home Depot, Lowes, etc.
