    • Expensive!!!
This is the only brand I'll use in my pool. I had a bad algae problem a few years ago that drove me nuts. I switched to the Clorox brand and was really impressed. These keep all algae away for a nice clean pool. But chlorine has really gone up in price, ridiculous!

    • Clear Pool
As a weekly maintenance item to maintain the proper chlorine level, this product works well. I add one tablet to my floater per week in a 30x15, 15,000 gallon pool. It has an excellent price per tablet, and I have not found much difference versus other tablets either way. The tablets are individually wrapped and are in a secure plastic container. I note that you MUST use rubber gloves when opening the container, and when opening or handling the tablets. Even a small amount of dust will burn. Also, the fumes are extremely bad in the container. Do not store this or open the container inside your home. ... show more

    • They changed the packaging
This is a good value for the money and you get a lot of tablets. However, the tablets used to be loose in the bucket. It was very easy, I would just use tongs to grab a tablet and drop in my deck chlorinator. Now, they individually wrap each tablet in a little plastic baggie. I have to use my hands to open the bag, which I don't like doing because I don't want to handle the product with my hands. That chlorine smells gets on my skin and takes a long time to go away. Washing with soap doesn't help. I wish they would go back to the old packaging. ... show more
