Natural Chemistry 20501PRO Phos Prevent-Phosphate Remover, Pro Series, 1 Gallon

This product is amazing i followed all the directions and my pool cleared and all the algae was gone. This product gives you step by step and if you understand what the directions mean you can youtube the product and there are people that explain how it works.

Works great on my pool. It keeps all the algae out of it. No complaints. I’m happy with my purchase.

After a very hard winter in CA that puts tons of debris in my pool my phosphate levels were sky high. The high phosphate levels were making it impossible to keep my chlorine levels up. In the past I have used the Pool Perfect® + Phosfree as a maintenance item. In this case I purchased this product and it worked well. It took several applications and 2x of cleaning my filters but my phosphate levels are now on the decline and the algae and chlorine levels are now getting better. I will make a better effort to keep the pool covered this winter and keep all the debris out so I do not have to deal with this issue next year.

If I could give this 0 stars I would.. This does even remotely work like it says it does! I thought maybe cause it said "commercial " that it would be a great product.. Terrible product.. It didn't even last a 2 months in my little 20k gallon home pool

This product is used weekly to prevent and remove phosphorus elements from swimming pool water and only requires a small amount/10,000 gallons of pool capacity. It has kept the pool water clear and enjoyable.

Good price. Quick delivery

Had a bad phosphate problem, this resolved it in a couple applications. Now we add some regularly to make sure it doesn’t come back. Great stuff.

Bought this product because it claims to remove 5100 ppb in 10000 gal pool with only 8oz of product. I have used other products that claim to remove "10000 in 10000 gal with 32oz of product or 5000 ppb in 10000 gal with 16oz of product. Adding the 8oz only got 1200 ppb removal vs. the claimed 5100 ppb. Had pulled water sample so also tested another 10000 ppb formula on same water using 8oz dose rate and that 2300 ppb so 2x as strong in performance and accurate according the that bottles label claim. This just seems like false advertising!!!label says according to lab test, but I have a lot of experience with these products, I would love to see that lab data because it performed for me at 1/4th the performance rate.
