Product is great and have purchased from Sams several times over the years, I do have one issue with my purchase. The Chlorine Tablets were on sale on line but not in store, I tried to purchase in store at sale price and wasn't able to because price was much higher. I ordered online and picked up at the store at the sale price which did not make sense to me.

PLEASE read this review all the way through. I like saving money and I buy lots of Sams and Members Mark products. Pool chemicals shouldn’t be one of them though. Here’s why - The total active ingredient (chlorine) is much lower than better name brand tablets. Your thought process may be like mine - “just use more and with the $ savings it’s still cheaper”. The problem is with how much stabilizer, or CYA (cyanuric acid$ you’re putting in your pool. All pools need about 30-50 ppm CYA, or the sun will eat up your chlorine. Too much CYA and your chlorine becomes ineffective. Think of CYA like sunscreen.....you want a tan but you don’t want to burn. Don’t use any and you burn, use too much and you can’t tell you’ve been in the sun. CYA protects the chlorine around when it’s around the 30 ppm level, but once it gets over 50+, you have to start using more chlorine for it to be active and work. These tablets are low on active chlorine, but very high on stabilizer (CYA). We used these for a season and it worked fine initially, but had to start adding more tablets each week to prevent algae. I started researching and discovered the CYA piece. Bought a test kit that measured CYA and we were over 200 ppm. Normal chlorine levels are around 4-6 ppm, but with our CYA over 200, we had to use three times as much chlorine for it to be effective, and this led to adding even more CYA since it’s so highly concentrated in these tablets. CYA doesn’t go away, you have to drain your pool and refill with fresh water to get your CYA level back. I learned the hard way and spent lots of money on pool chemicals because of this. I also spent lots of time and money partially draining my pool a few times to get the CYA level where it needed to be.

These chlorine tablets contain trichloro-s-traizinetrione which increases your cyanuric acid which can cause chlorine “lock” and it's unsafe to swim in when levels are high. I've had to drain my pool half way to lower the number and had to go to a different type of chlorine tablet.

tablets were wrapped individually but aloy of them are broken

Chlorine Tablets. Work just fine

About 15 of the tablets were in pieces. Less breakage when bought previously in the store.

This is a great value. They are individually wrapped and easy to open.

Individual package tablets

Best price for chlorine tabs

I’ve used this every year for 5 years and I enjoy that each tablet is individually wrapped
