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.
