### ⭐⭐⭐⭐⭐ Shock treatment that works great in our pool.
*by A***S on March 16, 2026*

We've been using this brand of shock treatment for our above ground pool for several years now. It works great and is affordable for us. Have never had an issue with it except when we forget to put it in the pool lol! We only use this for our pool. We do not use any chlorine tablets or anything else. 1 bag once a week keeps our pool crystal clear, even in our hot humid and sometimes very Iowa climate.
