WOW - Best Purchase Ever, December 14, 2008
By mbw714 from Phoenix, AZ

Pros: Easy to Use
Cons: None to Date

"I bought this product hoping to better manage my potential algae problem during the summer when on vacation. Sometimes my husband forgets to check the chemicals if I'm out of town and I would get to come back to an almost green pool. Now it's simple, a few capfuls in the skimmer before leaving and I come back to a worry free pool. I haven't had ANY algae problems even with the solar discs on and leaves in the pool! Simply amazing!!!"

Best of the best!, August 22, 2007
By KPCounty

Pros: Must have!
Cons: None

Phos Free saves $$$$, August 22, 2007
By Patrick from Grand Rapids, MI

Pros: I use WAY less shock!
Cons: None!

"I use this stuff, and shock @ open and close of season ONLY, and have GORGEOUS water all summer long! Just balance water @ opening, keep 3" tabs in your skimmer, and add a little PHOS FREE whenever you (or Mother Nature) adds water! GREAT STUFF!!!!"

Outstanding Product!!, August 22, 2007
By DalGalJr

"We have struggled with algae problems for the past 3 years in the summertime heat. However, a friend recommended this product and we thought we would give it a try, however I was very skeptical. Ordered Phos Free anyway and WOW, what a difference in our pool. Sparkling Clean and no more algae problems! Highly recommended!"

Phos Free is a must to pool owners, August 12, 2007
By MCAGM from Columbia, SC

Pros: Great asset to your purse
Cons: None

"I had a pool build last year. I struggled with yellow algae to the tune of over $1,000.00 in a course of two months. I couldn't use the pool most of the summer. I went to several pool stores to purchase chemicals. I used banish and all sorts of things. I close pool for the winter and started over this year. To my amazement, finally someone told me about Phos Free. I mean in a matter of two days with a 20x40 pool and 16oz of Phos Free my pool is perfert. No more algae. I can't begin to tell you how fustrated I was. To anyone out there, I promise you; this is the best thing since the microwave."

algae killer, August 10, 2007
By susan

Pros: keeps my pool clear and sparkling
Cons: none

"Before I discovered Phos-free, my pool kept getting algae all over the sides. I kept adding more and more chlorine, but nothing helped. I was told I should try Phos-free, and what a relief. The pool cleared up within a few days. I now use Phos-free regularly and I never have a problem with ugly green algae anymore. My pool looks great. I highly recommend this product."

Great product!, August 10, 2007
By cjpbsn

"I used this product last year and did not have an algae problem all season. I even used it during pool closing and no algae grew all winter. It made reopening a lot easier this year. I did not purchase the product this year until after I experienced a bad algae problem. I will never be without this product again!"
