HTH Pool Care 3" Chlorine Tabs Advanced, Swimming Pool Chlorinating Sanitizer & Algaecide, Kills Algae and Bacteria, 5 lbs

Love this product. Works perfect. It keeps your pool water completely clear. It is a shame that they won't ship it to Puerto Rico anymore.

The only downside is getting these out of the plastic case even after the initial opening of product. Once it's closed it's still very hard to open.

Good for price

Puts chlorine in the water along with stabilizer to get your cyanuric acid up. So it does exactly what it's supposed to do. Like other reviews though, half the tablets will come broken up into crumbled pieces. Doesn't really matter. You can put everything in your chlorinator the same way. Would be nice if they were a little bit cheaper especially since it seems like they're selling broken ones at full price when they should be considered slightly defective and cheaper but whatever. This is way cheaper than the pool stores. Especially if you're like me and only needed 8 to 10 tablets to get that stabilizer level up to where it should stay for the rest of the summer. No point in buying a $200 bucket to only use a few of them.

I always buy these from Amazon because they're much cheaper than the pool store and they're exactly the same
