Product Description

Clorox Pool&Spa XtraBlue Chlorinating Tablets go the extra mile to help maintain healthy pool water. These multi-functional tablets work hard to keep your water clear from both bacteria and unsightly algae. Each tablet dissolves slowly and contains stabilizer for a long-lasting clean. The XtraBlue Formula protects your surfaces from scale and corrosion, and includes conditioners that make your water feel silky smooth. Maintaining 1-4 ppm* of Free Chlorine is critical to keeping water clean and suitable for swimming. Use weekly in skimmers, feeders or floaters. Always apply chemicals per label directions. Circulating pool water when applying chemicals helps disperse chemicals throughout the pool for maximum coverage.

I like that these tablets are not wrapped in plastic. The plastic seems like a waste of money and retains any moisture. These tablets are a better buy per pound than many others.

4.0 out of 5 stars 5 pound container holds 10 tabs. So about $4.50 each.
Reviewed in the United States on October 25, 2023
Style: Loose TabletsSize: 5 LBVerified Purchase
5 pound container holds 10 tabs. So about 2/3 of the container is empty so just enough room for several to be broken up. Still usable but not sure why they have to put 10 tabs in a container that can actually hold at least 4 times that.

Also with only 10 tabs at a price of $45 per container, before tax, that's $4.50 for each tab. Seems very expensive. The ($0.54 / Ounce) thing is cute but price per tab is what you need to look at if you use several tabs a week especially in hot weather.

5.0 out of 5 stars Best bang for the buck of any brand that I've tried
Reviewed in the United States on January 3, 2023
Style: Loose TabletsSize: 35 lb.Verified Purchase
So I was lucky enough to catch these in late December '22 for almost 50% off by using a price tracker. Obviously I jumped all over that given the prices over the last couple years and bought two 35 lb pails. It took them quite a while to get here UPS, but even though the tabs aren't individually wrapped and came cross country they were in good shape. 72 tablets, one broken in half, and a little bit of powder in the bottom. No worse than if I'd bought it from a local store. I've tried quite a few different brands and either this or the Super 99 Clorox brand have work the best for me. One year I ordered 50 lbs from a pool supply company that starts with a D based in Wisconsin, and even though they had supposedly the exact same ingredients I had more algae that year than I've ever seen and just could not get rid of until I switched back to Clorox. Given the amount I ordered I knew I needed it to keep for at least a year or two, so I decided to bag them myself. I had a bunch of mylar 1 gallon long-term food storage bags and a heat sealer so I did four tablets per bag for a total of 18 bags. I may do the second container as well that way. At least that way I know they're airtight and they're not going to off gas. Anyway, I highly recommend them but I would also recommend tracking the prices because they do come down, at times only for a few hours, but if you can catch them it's a pretty smoking deal.

3.0 out of 5 stars Great product, BUT, tablets may be broken and/or crushed during shipping.
Reviewed in the United States on April 10, 2024
Style: Loose TabletsSize: 5 LBVerified Purchase
The Clorox tablets themselves are very good. The container was sealed and enclosed in a plastic bag for extra protection during shipment, then placed in a box for shipping.
There is no extra cushioning, and during transit many of the tablets were broken into both large and small pieces and powder residue.
Better protection needs to be used including marking "fragile" when shipped.
