Natural Chemistry

well made product and worth the money. A cap full every week and it eliminated any issues with Algae, without having to over chlorinate. The bottle lasted all summer.

Our pool is situated near a large apple tree and gets numerous leaves in it all summer. Along with pollen adding more debris, the Phosphate level in the water causes green algae to form quickly, and algaecide does nothing to alleviate the problem. Heavy shocking doesn't help either. Google told me the algae feeds on the phosphates and a Phosphate remover should help. Well, it did! From green growth all over the liner to crystal clear water with no visible algae on the walls within 2 days. A quick vacuuming to pick up the dead algae, and all is well. Great price, effective, and there's enough in the bottle to last a couple years in my 18 foot above ground pool. 5 stars!

I've used it in my pool for years. I keeps the phosphates down which helps fight off algae growth. I use it in conjunction with Pool Perfect. I also use Metal Free to stop my kids blonde hair from turning cgreen from.

This product works well, but I found that I have to use it more frequently than directed to maintain an algae free pool in hot weather. Above 90° it was needed every day.

Works as advertised good product.
