42056W, Swimming Pool Care 3" Chlorine Tabs Ultra, 8 lbs

It quickly cleans pool water and leaves a good PH in the water. Beware buying from anyone but Amazon. I've received counterfeit product and products intended to be sold only in Canada. Images I uploaded are from a product sent by Seller Sensation. It was frustrating to need product and have Sensation send the wrong product to me, be forced to return it and buy another product.

These are working great on my pool. They were more economical than the others.

Good quantity

First time using it and very impressed with the results. Will continue to purchase.

Ordered these for my pool . Was not aware there are commercial and generic make up of pool products. This works fine in my pool skimmers for chlorine added to the pool but are smaller than the commercial brand I use and do not last quite as long. A good product but probably better for a smaller home pool than mine, which is about 32,000 gallons.

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.

This is just chlorine. Not the 4-in-1 advertised. Contains no zinc sulfide as advertised or other chemicals to treat and soften the water. 2nd time Amazon has shipped the wrong product. Buying from Walmart instead. Not even the advertised product number. Garbage.
