HTH 42053W Pool Care 3" Chlorine Tabs Advanced, Individually Wrapped Tablets - Swimming Pool Sanitizer with Clarifier & Algaecide, Destroys Bacteria & Algae, Delivers Clear Water All Season, 8 lbs

These 3-inch chlorine tabs are my favorite because they are the best quality of all the brands I have tried over the 3 years I’ve had my pool. They come perfectly packaged, individually wrapped so that they last until you can use them. Simply unwrap them and put them in your chlorinator or your skimmer. These tabs last about a week before I have to replace them in my chlorinator. They keep my chlorine levels always at ideal, too. Thank you for the easy and clean product!

30 year pool owner here, let me tell you that nothing is saved with the cheap chlorine tabs. You’ll use twice as many and still constantly be battling low chlorine levels. HTH is worth every penny and cheaper just to have Amazon bring it to your door

Ordered at 9:00am. Arrived at 12:30pm same day. Keep in mind that a 5 pound tub is about 10 tablets, so this is a ten week supply for a smaller size ( Mine is 15' wide by 30' long by 5' deep) swimming pool.

So far new pool set up for about a month near the edge of a clearing with tall pines close by.pool is clean very large above ground and only vacuumed three times in the past month! I would have to say both products between the chemical cleaner and the pool fiber balls have kept algae at bay. Note: weekly shock after heavy use or rain.

A few tablet packages were open, so powder was all over the other tablets. I'll survive.

I’ve used these tablets for years. They work well with my pool shock to keep my pool balanced.

I like it work very good keeping my pool nice and clear.

I was having a problem with chlorine levels in the pool. One tab in the skimmer basket does the trick.
