Have used this product for many years. It is high quality, it dissolves and elevates the chlorine levels in the pool quickly. Great to shock your pool or when you have to bring the chlorine levels up rapidly. I highly recommend it

Quality

Does not seem to be same potency as that which we purchased here last year. Needing to use more to achieve same results. Could be weather but up to now, it has been unseasonably cooler than last year.

Good price, low percentage active ingredient

Sams has the lowest price on chlorine granules of anywhere I've found, however my pool guy pointed out that the percentage of active ingredient is much lower than other more expensive brands so I have to use twice as much for the same result.

What Changed?

I have been using this product since we installed our pool in 2009. I would use 50lbs a year. I have gone through 50lbs in 5 months. Only thing I can figure is the available chlorine has been lowered to save cost. I understand that the cost is out of Sam's control.

Spend more for quality

I usually don't deviate from my original brand, but 50lbs for the price that Sam's was offering, was hard to pass up without giving it a try. So I had my water tested and my pool required 12-15 lbs of chlorine granules (shock). I put in the recommended higher dose of 15 lbs. Two days later I had my water retested and the test recommended another 10 lbs of shock. So I added about 12 lbs to be sure - and my water has yet to show progress after yet another 3 days. All other opening methods of back-washing daily and brushing have been included. There is no algae or debris in the pool as I have the filter and a robot constantly running. I don't know if chlorine expires, but the bucket I bought seems to lack potency. Reconsider!
