Natural Chemistry Pool Perfect + Phosfree, 3-Liter (3-Pack)

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.

I have been using this weekly in my skimmer to keep my pool sparkly clean. So far, it has done a great job of keeping my chemicals balanced and my phosphates low. Much better price than my local pool store, and produced by the same manufacturer.

We’ve struggled with algae issues in our pool every summer, and it’s been a constant battle to keep it under control. However, since we started using Natural Chemistry Pool Perfect® + Phosfree, we’ve seen a remarkable improvement. The product has led to a sharp decline in algae growth, which has been a huge relief.What sets this product apart is not just its effectiveness in addressing current algae problems but also its ability to help prevent future growth. This dual-action approach has made pool maintenance much easier and less time-consuming. The fact that it comes in a two-pack is incredibly convenient, offering us a good supply for regular use at a reasonable price. The cost is comparable to what we’d pay at local stores, making it a cost-effective solution for pool care.The ease of use and noticeable results make this product a standout choice for anyone dealing with algae issues. It has truly transformed our pool maintenance routine and provided us with clearer, cleaner water.Overall, I highly recommend Natural Chemistry Pool Perfect® + Phosfree. It’s an essential product for anyone struggling with algae in their pool, providing both immediate results and long-term benefits.

Does what it says. Algae doesn't take off so easily. However, I thought this would be like the "weekly" liquid had before that you can add each weak without backwashing, but you have to: (1) add a considerable quantity, (2) run your pump for 48 hrs, and (3) backwash. Major pain compared to the weekly stuff. That said, it is effective.

This product is awesome!! Weekly maintenance and the pool is perfect.

This is a great product for lowering the phosphate level in swimming pools (and therefore reducing the chance of algal growth). An added bonus is that the pool is crystal clear after application. Our local pool store sells their own brand of this at a much higher price!

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.

I have been using this product for decades. It keep algue at bay. It works even better in a salt pool.

I've been using this product for 10? years and have NEVER had an algae bloom since I started using it. Next to water, this is the most important thing I put in my pool, I also use it in my hot tub. Great product!

Been using this product weekly for years. Well worth the price.

Pool is clear and clean. Remember to follow instructions.
