I've been a pool owner for 15 years and this product has been a game changer! For years I fought yellow and black algae infestations spending 100's of dollars for pool shock and algaecide treatments as they occurred from time to time even though I maintained the pH and chlorine levels religiously. The black algae is the most insidious as many may already know especially for an in-ground plastered pool. Once it permeates the plaster (especially older plaster that has become somewhat porous) there is little hope of removing it completely even with constant scrubbing and treatments. The jet black stains remained no matter what I did.

I discovered the best answer by visiting dozens of pool blogs on the internet. The answer was in the phosphate levels. Recommended levels vary but most pool store tests advise 0 to 300 ppm. Algae of all sorts thrive on phosphates (it's like fertilizer to them) and the hidden truth is you want zero (0!) phosphates period! Of course algaecide and shock treatment manufacturers don't want you to know this therefor the 300ppm recommended upper limit. That's way too high.

Last year I purchased a bottle of Natural Chemistry Phos Free for the initial treatment to eliminate phosphates and a bottle of Pool Perfect + Phos Free for weekly maintenance and have continued the weekly maintenance since. The results have been amazing! Algae infestations have been eliminated (knock on wood!). Even the permanent black algae stains have faded until they are almost imperceptible with no additional scrubbing required. It took a couple of months for them to fade so don't expect overnight results, be patient, it works! I highly recommend these two products.

This product is a nice complement to a normal pool maintenance program. I have read enough experts that agree - keeping phosphates out of the water helps on many fronts.

Product is simple to use and just works!

Had to re-order as the first shipment was lost in transit. But the 2nd order arrived in a few days. It's a brand name product at a very good value. Very happy with it.

4.0 out of 5 stars If the algae keeps coming back even using pool shock or algaecide, you need this
Reviewed in the United States on June 13, 2024
I went a few years with no issues but then starting getting a lot of algae. I didn't understand why as I would test my chlorine and pH every 2 days and have Pinch as Penny do a more complete test twice per month. All my numbers were in balance (chlorine, pH, alkalinity, stabilizer, calcium hardness, TDS, etc). So I tried an algaecide first but that was a band-aid, then tried the shock method, where you spike your chlorine for several days and scrub the wall daily.

That did the trick...so I thought. In a week or two, the algae would come right back (mostly green and yellow). The pool guy at the store insisted that I was not shocking enough, like I was the idiot. He told me I had to do it weekly. The problem is that the chlorine level would be too high for most of the week to swim in and I was going through a ton of chlorine. Plus, the upkeep was becoming a PITA.

I finally met up with a pool inspector and told him what was happening. He said, "I bet you have high phosphates". He told me to buy a phosphate remover and if the water immediately starts to get cloudy, that's phosphate. Sure enough, it turned cloudy right away. Running my pump non-stop for about 3 days cleared everything up. The pressure on my pool filter spiked due to the trapped phosphates, so I cleaned the filter and the pressure went back to normal.

So zoom forward 2 years later, I know have crystal clear water and use a lot less chlorine and no algaecides. Too keep my phosphates at near zero, I use this product as a preventative and shock the pool only about once per month. If you already have a phosphate issue, I would use a dedicated phosphate remover, then use this as a maintenance.

The is an excellent product to obtain crystal clear water. Organics be it pollen, pee or what have you will grow in non treated water. Of course Chlorine is the number one antioxidant , but add a touch of this to the cocktail and you will be swimming in gin clear water. 3 inch chlorine tablets and a couple of cap full of this, and you are golden.
