Naturally Blue Pro Phosphate Remover, 1 Quart

Works as advertised. Easy to follow directions. Water clarity is noticeably better since algae starved. Regular maintenance schedule is easy to follow.

This stuff totally works! To think how much money I’ve wasted on other phosphate products in the past before I knew about this stuff. I had extremely high phosphates and have used phos-free and other products before that didn’t do a thing. Just 2 treatments with this stuff and my phosphate levels went down from >1000ppb (the highest my test kit reads to) down to 50ppb. I still have half the bottle left for maintenance too. Definitely recommend this product!Update: I have had zero algae grow back since using this product. I have been battling algae growth for 2 years. This took my phosphates down to zero and the algae is totally gone! Super happy I read the reviews on this product and bought it.

I recently had our pool water tested for phosphates at a well-known nationalchain of pool supply stores. The phosphate level reported was 1701 ppb. Inorder to remove the phosphates, I purchased a 3-liter container of amuch-advertised product claiming to "work in the filter" to remove phosphates.Following two separate applications of the product (48 oz. of the product addedduring each of two different applications) to my pool of 8000 gallons and thenrunning the pool continuously each time for 48 hours, followed by cleaning thefilter cartridges, the phosphate level was reduced to only 720 ppb., stillwell in excess of the recommended maximum of 100 ppb. I then purchased and tried"Naturally Blue Pro Phosphate Remover". I added only 4 oz. of the product, ranthe pool filter for 24 hours, and verified that the phosphate level had droppedto 0 ppb. I highly recommend this product.

Easily lowered my phosphate level in my pool.

I ordered another bottle. Worked assume and so much less expensive than others bc concentrated.I was at 2400 (wow) and added 8oz and it dropped to 1400 within 48 hrs. Added 8oz again and it dropped to 400 within 48 hrs. Added 2 oz and I’m at zero phosphates. I ran filter 48 hrs straight after adding each time and this was all done in Sept 2021 in Texas. Very happy.

Wow one of the users left a really comprehensive review so I was convinced. My phosphates were over 3000 for a couple of weeks I tried everything. I finally got a hold of this product added it to my pool now I’m down to zero. Now I just have to figure out how to finally get rid of the algae. The bane of my existence. This is definitely concentrated and much more economical than all the other products out there!!

I have been using this product for 3 years. I had zero experience before with pools so I have not tried other products. My pool is always so beautiful and clean!!! I use 2oz once a week direct on the the water when the pump is on and my pool is around 13000gallons.

I can not find this anywhere but here on amazon so I was skeptical. But compared to Pho Free or the other stuff Leslie's sells, this is amazing. With the store band stuff you are paying for water. For my 18k gallon pool my level was ~500 ppm. 4 oz of this stuff and the level was down to 0 in 24 hours. Actually checked it twice be sure it was not a testing error. Leslie's advised I needed nearly 2 100 oz bottles of their potion. I still have 28 oz left- enough to do this 7 times over or more. And for less $$.
