Naturally Blue Phosphate Remover, 1 Quart

I’m sure this is fine, but it’s not as cost effective as the Pro version that I prefer. This takes 6 oz for 0-500 ppm vs the Pro version of the same thing that takes just 2 oz. Just make sure you’re ordering what you think you are!

It did not reduce Phosphates they actually went up. I contacted the seller and they were helpful and indicated they thought the phosphates broke up and became larger for easier pickup in the filter. Could be. I replaced the filter and bought a competitive brand and they were gone.

Reasonably priced and concentrated as compared to other pool product retailers. Works well and has no expiration date as other phosphate removers do. (I would not store Naturally Blue Phosphate Remover at a location where it may freeze)

Used as directed, did not help reduce phosphate at all. waste of money

Got rid of my phosphates after when used in conjunction with filter cleans a week later. Better deal than that water down name brand junk.

Great product ,Takes less then recommended by the pool store .Will definitely repurchase when needed

I used the bottle to hopefully cut down on the phosphates in my pool this morning, but got none of the normal cloudy reaction that would show that it was working. I'm afraid that I wasted my money on this product.

Concentrated, so lasts twice as long as Leslie’s $40 bottle.
