Chlorine tablets

These chlorine tablets are easy to handle and use in your chlorine floater. They last about two days and they do the work they’re supposed to do when I test the water. It always comes out correct I would recommend this to anybody who has a small above ground pool for their grandchildren or children.

Perfect for my inflatable hot tub

These HTH 1” chlorine tablets are the perfect size and strength for my inflatable hot tub. They dissolve slowly and consistently, keeping the water clean, clear, and odor-free without overwhelming it with chemicals. Super easy to use with a floating dispenser, and I’ve had zero issues with cloudy water or buildup. Affordable, reliable, and a must-have for hot tub maintenance!
