Bests & Worsts Reviews from Amazon

Ordered the "small" bucket of this to try out the Clorox pool line. The 5lb bucket received was already open (the security band was not there) and it had more tablets in the bucket then it should have (13). I can only assume someone is refilling 5lb Clorox buckets with a cheaper plain chlorine tab. But who knows what is in it. And that's a safety problem. I have been the victim of altered pool products twice now and feel it is becoming a serious issue. For example, on another occasion I received a product that had the seal missing and was diluted with, hopefully, water. But without a lab to test it, who knows. That is the key problem, IF you get a mislabeled/counterfeit chemical product you could unwittingly cause a deadly chemical reaction with what is already in the pool. Saving money is not worth even the smallest risk. From now on I will be ordering only from pool suppliers instead of risking Amazon 3rd party garbage. The price of this bucket was on par with standard retailer prices so I wasn't saving anything but time getting this off Amazon anyway. Also, since I am unsure if I really received the CLOROX product I wanted to try, I will have to find another supplier to see if this line works for me on algae control. Ugh.
