“Love it. Recommend it no regrets! I did bunch of research. Pool stores really don’t know this product. Very few pool service companies know about it. I’m a first time pool owner and take care of my own pool. I test my water in the pool store once a month for reference and test it on my own every week. They told me I am the only person that hasn’t complained of algae problems. Baking soda, acid from pool store, tablet one a week in float. Water smells like a river after swim”
