Problem Solver,

"My pool environment is challenging: sun, rain, heat, lots of organics. My well-known algaecide was working, but not at the recommended maintenance dose. With Phos Free, no more problem. No more expensive high dose of algaecide for "visible algae". One more product, but less expensive, more effective overall maintenance. If you have any questions or concerns, simply call the 1-800 number on the container."

Effective phosphate killer,

Pros: This will stop phosphates fast and keep your pool algae free.
Cons: Need to add incrementally to sand filters or psi will ramp up.
"Phos Free has been my go to product for the past two years. It will take water with over 1000 ppb phosphate to less than 100 ppb in about five days or less. Used consistently it has kept our pool clear and algae free."

Cons: This product will clog your filter in no time flat
"I purchased this product in the Ultimate start up package. The moment I dumped this into the filter it shut down. ( I have a DE filter ) I had to pull the filter apart and wash all the product out. It hasn't worked the same since. I would not suggest the use of this product to anyone."

Pros: Great Customer Service
Cons: Filter Clog
"Similar to another poster, I followed the instructions and it clogged my DE Filter. I tried to bump it (it's not bump capable). I wound up having to completely backwash the product out. HOWEVER, I was still pegging a 1000+ p/bb on Phosphates - so I thought I'd give it another try. I called their customer service department to ask how to proceed. Not only did they offer a solution - they provided some free maintenance product after I bring the phosphates down. It always help to call! I'll try and do a follow-up post after my next batch. Therefore, if you have problems - definitely call the vendor; they appear to stand strongly behind this product."

PhosFree Believer,

Pros: Crystal clear water, no harsh algaecides & sooo easy
Cons: Cost
"9 year user. Got first sample from my pool builder. I hate the dangerous chemicals in algaecides, and don't like the foamy water, algaecide taste or water ring from dead algae.
Open pool with shock & algaecide. Vaccuum and clean the waste. Balance pH, test phosphate. Use phosfree if elevated, then weekly phosfree + pool perfect. Keeps water sparkling with no foam, no water ring and no algae, even through August. Will occaisonally add a dose for unusually hot weather or a lot of rain.
(I don't find the spring / fall treatment to be useful. Even with use at recommended dose, still need algaecide to open.)"

"This product clogged my cartridge filter so bad I had to replace it. It was so full of goo & drastically reduced my flow! I researched it before I bought it & said it would work with all filters. NOT SO! Cost me $100 bucks for a replacement cartridge. Not happy at all!"

Pros: Really works as claimed!
Cons: none!
"I had a very large problem with mustard algae last year and tried to fight it off with just chlorine which was a failure. Proceeded to go to all pool stores around town for advice and chemicals. I was given all kinds of chemicals to kill this stuff including but not limited to copper. Copper is excellent at killing algae but get too much in your pool and you will have problems. It got so bad with the algae (phosphates were above 1500) that I gave up at the end of the season and just closed it. Upon opening this year, it was just as I expected, a big mess. Phosphates were above above 1500 again and thats when I decided to try this product along with a lot of chlorine (6lbs for 17,500 gal. pool) to kill the algae. This product does NOT kill algae and keep that in mind. It will however keep it from coming back once you do kill it. You have to keep the chlorine levels very high to kill it and also put this product in as well. I went through 2 bottles of this product and my chlorine level is at 43 which is way high but it eliminated my problem. Word of advice....go to the pool store and have them test everything including the phosphates. If they do not test for phosphates, go somewhere else that does. It will pay off in the long run."

"Phos-free works great. As soon as I put it in our pool we stopped having problems with algae & the water turned so crystal-clear that the water looked shinier than it has ever been. This is a big must-have."

Finally!,

By ihatealgae

Pros: Easy to use, the missing link to algae control
"With arthritis, we keep our pool warmer than the average pool. This results in a struggle with algae. Our pool has been either green or cloudy most of the summer- yuk...and we have spent hundreds of dollars on chemicals. This would have been tolerable if it had resulted in clear water. I even replaced fairly new filters, thinking this may be the answer. I saw this product and thought the mechanism of action seemed logical. Well, we now have the clearest water we've had in 7 years! I anticipate a great decrease in the cost of operating our pool....and it is beautiful now."

"I have been reading the reviews for Phos free for 2 year now, and thinking to myself " right, I bet it doesn't work on my pool". Boy was I wrong! It works like a charm! After fighting algae so long, you start to wonder if it is even worth opening your pool for the summer. Thanks Phos Free for letting us enjoy our pool and our summer again"

Pros: Keeps pool completely Algae free

"I have owned a pool for 24 years and this year was the easiest year I have had. Some years I have had to fight Algae no matter how perfectly balanced I kept the pool.
This year I started using PhosFree and I haven't had one bit of Algae and my chemical usage has been cut in half.

Worth the money,

By Polly
Pros: Works great and is easy to use
Cons: none
"Our water would turn green and those little carnivorous bugs would appear. We were fighting a losing battle. Finally we asked a friend what he used and he recommended PhosFree. He also said if the water was clean, the bugs would leave. We used PhosFree and he was absolutely right. Now we just use the weekly maintenance dose and we have crystal clear water, no algae and NO bugs!"

Pros: Easy to use and very effective
Cons: don't forget to shake it before using!
"We had an ongoing algae problem that we couldn't seem to overcome. We would get rid of the algae for a while, but it kept coming back. Someone recommended we try Phos Free. You have to get rid of the algae first, and then start using Phos Free to prevent the algae from returning. Well, this has really helped us to keep our algae in check. Hooray for Phos Free!"

Pros: works like a charm
Cons: none
"It is now a known fact that algae cannot survive without phosphates, and Phos-Free easily brings your pool's phosphate level to zero. Since using this, I have never had even a hint of algae (and it was a significant fight before then). Plus, the 3 liter bottle from In The Swim costs about the same as what my local store charges for a 2 liter bottle. I usually get 2 bottles (which meets the free shipping level) and I'm good for the season. Not only that but a free test kit is included so you know it's working. All around, my favorite item from In The Swim."

Pros: Easy to use
"Adding this product to my very green pool was the only thing that worked against a bad algae outbreak. High levels of chlorine and addition of algaecide had no impact. It took one dose and two days later the water was clear. Subsequent small weekly doses have kept the algae at bay."

Pros: Water feels great, no algae, no little water bugs
"I use both Pool Magic and this so I can't say for sure which product does all this.....my water feels so soft, everyone who swims here mentions the "soft" feel of the water, no algae ever, I still clean the bath tub ring area of my pool once a year with the natural spray cleaner but many people wouldn't think there was a need to clean it it stays so clean with these two products. And I don't have all those little water bugs that used to "bug me" in July and August in the the Deep South."

Pros: easy to use, reliable results
Cons: a bit expensive
"THis product(along with all the associated ones) helped to clear my pool of high phosphate levels that were introduced by a metal/stain removal product. (Which I will NEVER use again - and only did because my pool company said it was the best to get rid of the staining BUT obviously didn't know that it was phosphate based and caused an almost irreperrable problem with my water !) No one at my pool service company knew what was wrong with my milky colored water. I discovered this through some research and boy am I glad I did ! I am a faithful user and you should be too!"

Pros: Everything
Cons: None
"This is the second year that I have used Phos Free in my pool. I have to say it is the most amazing, time and money saving product that I have used in my pool. I have had no problem with algae, the pool is cleaner, I use far less chemicals, the water simply sparkles and is as clear as a bell. My usual two to three week pool opening this year was reduced to 5 days (using a lot less chemicals and $) thanks to closing last year and opening with Phos Free this year. It is worth adding to your weekly routine. In the long run this product more than pays for itself by using fewer chemicals season long. I am a believer and have the $ to show for it! Good luck. On a side note - the water is so clear after using this product that I can see the smallest spec in the deep end - it is like crystal!"
