Features
- Reduces Phosphates: Natural Chemistry's Phosfree enables pool owners to drop phosphate levels in your pool to almost nothing.
- Clear Water: PHOSfree works in the filter to minimize any water clouding, ensuring the water stays sparkling clear.
- No Phosphates, No Problem: PHOSfree is formulated from lanthanum (rare earth) compounds. When added to your skimmer, a thin coating of PHOSfree forms on the filter media. As pool water flows through the filter, phosphates are reduced to very low levels due to the lathanum and phosphate molecules sticking together. Works inside the filter which means less clouding of the water.
- Effortless Maintenance: Simplify pool care with Phosfree designed to reduce overall maintenance while keeping your water clean and clear.
- Tested and Proven Effective: Natural Chemistry products are known for delivering reliable results and making water care less complex. Natural Chemistry carries an extensive line of pool and spa solutions that match your unique needs.

We had a green algae problem from middle of last year onward. I would get algae along the bottom of our walls even though my Free Chlorine, PH, and Alkalinity were all perfect. I would by some Green to Clean, which would get rid of it for a bit, but then it would come right back days later. Eventually, I just closed the pool last September and blamed it on something wrong with our DE filter. This year, our filter broke so we got a new one (DE again). Same freakin' problem with Algae. Spent another $100 on Green to Clean and Chlorine, and the algae was still coming back along the bottom edges first - and then up the walls and along the floor. After reading a ton of reviews everywhere, I bought 2 bottles of this product. The pool was a pretty bad color of green about now, but we tested and poured the right amount noted this in anyway. We tested in 48 hrs, and emptied/refilled the DE in our filter (no bumping, as that would release a lot of algae back into the pool). We kept doing this ~3 or 4 times over the week (test Phosphate, pour in recommended amt, cycle DE) and we are now back on track! It did cost me ~1 25lb bag of DE, some chlorine, and time scrubbing the pool to loosen up the algae, but it worked! The phosphate level is below 100 now, and the pool is crystal blue. I turned our pump down so it is only on 8hrs per day (energy savings), as well as not having to dump 2 lbs of shock in every few days in addition to my inline chlorine feeder - just to stay ahead of this! We only used up 1 3liter bottle getting our 27' round pool in shape, but we will definitely be checking weekly and using our 2nd bottle thru the summer, closing, and next year. Must have this stuff on hand at all times! NOTES: - If you have a DE filter, expect to cycle the DE at least every day until the pool gets clean. - Don't forget to stir. This is a milky white product, and we thought it was clear for the longest time because the white stuff was on the bottom. Thanks for all the reviews - a huge help! UPDATE AFTER USING FOR 2 MONTHS: STILL NO ALGAE!! This is amazing stuff! Buying some more now (1/2 price) to have on hand for next year. I agree with another reviewer - this is the best kept secret at any pool supply store. Even if you don't have an algae problem yet, you should still get this stuff because you don't want an algae problem. UPDATE AFTER POOL OPENING FOLLOWING YEAR: STILL AMAZING!! I put the rest of my 3 liter jug into the pool at the end of last year, and this year we opened our pool late (mid June), and there was still no algae. We measured the Phosphate levels again, and they were fine. We went right to a maintenance dosage this year. When we opened our pool late in prior years, the pool looked like a swamp. It used to have flies, frogs, and some other weird swimming creatures. We couldn't even see the bottom of the pool. Now, after using this - it is amazing. Will never go back, and I always have an extra 3 liter on hand now!

Love this stuff for my pool! Removes phosphates quickly, very effective! The easiest way to use this is to get a free water sample from your local pool store, they will tell you exactly how much of what chemical to add. The liquid looks like watered down milk, it has a white milky look to it. No odor that I detect. Not too harsh or hazardous, you feel safe using it. A jug of this stuff usually lasts me 1.5 - 2 seasons in the Northeast US.

I clean our pools. We live in a high wind area so the organic debris often collects, where else … in my pool … and thus the algae battle begins. I clean it quarterly. I use this Phosfree as part of the routine: half bottle in the skimmer the day before while the pump is running all day. The next day after cleaning the filters and salt cell, my pool is crystal clear. I use the other weekly product in my skimmer to help in between full quarterly cleanings. Highly recommend to control the phosphates in your pool.
