No issues with the product but prefer the tabs
4 out of 5 stars
No issues with the product but prefer the tabs
This was easy to use. We added a cap full every week and had no algae issues so it does work.However, we just prefer the multi function tablets in a floater now and I knocked a star off because the bottle leaked despite the lid being on fully! Didn’t do damage but made a mess in my pool box!
