    • Only brand I’ll buy!
Size: 25 LB
I purchased the 25lb pack during the Amazon specials a couple weeks ago. I usually use one to two tablets a week based on the temperature. It’s strong and does what it says. It’s keep the pool nice and clean. The price was cheaper than buying it locally.

    • Super clear pool all summer!
Size: 5 lb.
As a first time pool owner who knows absolutely nothing about pools or pool care, these have been an absolute lifesaver this summer. They work very well & have kept my pool Crystal clear all summer with minimal maintenance. I would not use any other chlorine tablets!

The tablets were wrapped Individually. I liked that, there are ten 3 inch tablets, in total more than I expected. The price was reasonable and the chlorine works perfectly for my above ground pool. It keeps the pool clean and free from algae. They last a week which is good. The size is perfect for my floater. ... show more

Crystal clear with minimal effort. Worth the cost. I also run the pump 10 hours a day and throw in some baking soda occasionally.

    • The only chlorine tabs I will use for my pool.
Size: 35 LB
I was pleasantly surprised to see each tablet was individually wrapped. This keeps them from losing their potency while sitting outside. The container is like Fort Knox to get into though. You have to rip the edge off to get the lid open, but also lift the tab to get the lid open. You have to be careful when opening because these tabs are powerful. The chlorine content is the best. They are the best to keep my pool blue and clean. I wish they were cheaper but they work so I can't complain. I put these in the hopper and these don't float. ... show more

    • Individually wrapped
Size: 5 lb.
They came individually wrapped. Not sure if that's a good thing or not. But I liked it. Work well and keep the pool chlorine levels in tact.

    • Great tabs but arrived broken up!
Size: 5 lb.
These are truly the best chlorine tabs I've ever used 25 years! But in the last two deliveries, the wrapped tabs were all broken up within the wrappers. The wrappers were slightly opened so there was dust everywhere when adding to the chlorinator, and small pieces dissolve too quickly.
