3 inch chlorine tabs

If you want a substantial number of 3 inch chlorine tabs, this bucket will do the trick. In the long run it is cheaper than buying by the little box. And these will stay dry.

Excellent chlorine tablets

These are great!! They are solid tightly packed individually.. they are all broken like when you have tablets shipped.. they last a good long time and keep your water clean and clear. They are highly recommended

Chlorine Shortage

Chlorine Shortage - bought one 40 pound container of tablets online last week. Free shipping and chlorine arrived early. And, then went to local Sam’s Club to purchase two additional 40 pound containers this week. Sam’s Club 40 pounds is at a phenomenal price when other merchants / pool supply companies are charging twice as much (or more!) for the same product.
