Small chlorine tablets for softeners

I use these for my water softener and brine tank. I have well water, and these definitely help with odor. When cleaning the brine tank, these work better than liquid chlorine. I followed the technician's instructions and added 4 tablets to the water cartridge. It is better to use them when the water level is above your salt, for the best distribution.

Great for well water systems

We use these in our well water system. We put about four tablets in a floating floaty in the salt container. I like the bottle that comes in for storage and it's easy to open. It gets the job done. We need us to help keep our water clean and not bacteria grows in our water system.
