Bests & Worsts Reviews from Amazon

I normally purchase Pool Essentials Pool Shock. https://amzn.to/2VsI5mm. I have always been happy with this brand. This particular box was listed as the newest "model." Sad to say that when I received it I realized that it was NOT the same. - A pound less of the product in total (normally 6 pounds, this is 5 pounds). - Less active ingredients (53.5% vs. 43.47%) - Less available chlorine (48.6% vs. 40%) This is not the same product that I have come to expect with Pool Essentials.
