I'm very happy with this purchase. It cleans the pool as expected and was the most affordable that I found on line. I have purchased this twice and it will be my go to shock for now on.

Dissolvability, easy to use, effective, and long lasting. My second season of using this product. The best shock I have used to maintain the pool in almost 30 years. Highly recommend the product.

I shock late evenings. It temporarily clouds the water when added but it clears overnight.

This chlorine is a lower rated effective ingredient than higher priced chlorine. It does not dissolve easily. It sits on the floor of the pool and you have to brush it to get it to dissolve. It does not work as well as others; we wish we hadn't wasted our money.

I went with the 50lbs… should last us a few seasons. This product does an absolutely fantastic job. Not much bad I can say about it. I have a vinyl above ground pool and haven’t noticed or had any issues with the vinyl being damaged. If you are worried about the chlorine smell or it even being in your pool don’t purchase. If you don’t have a problem with it great purchase. This dissolves pretty quickly… I mix it in a 5gal bucket with pool water then add to the pool. Also does a great job on removing the algae. If you go with the 50lbs know it’s going to be a big bucket.🤙
