We have had more difficulties with phosphate levels being higher this year, and it was much hotter, so we had more yellow algae issues.

We have used liquid phosphate removers in the past, so I wasn’t getting
the same performance this year. When I put a PhosLocker in, within a week or two the pools were all cleared up and looking great!

I love them, they are so easy to use and I don’t have to clean the filter afterwards.
A yellow algae bloom costs a lot to kill, so using PhosLocker® saves money.
