Would RecommendOur pool was so green with algae that we couldn’t beat for weeks. We had to get our CYA down first (back-flush the pool) pretty regularly (multiple times a day) for a week 5-7 days, and then fill with some fresher water. And then, When our CYA finally dropped we used this — and it was a game changer against the algae, crystal clear clarity now for a sparkling clear pool.

Great product for a green pool!
Would RecommendI use this regularly to keep my pool algae free. With Florida's rainstorms, heat, sun, a pool can go green in a couple days. A good brushing, this product, and liquid chlorine, it will kill the stubborn algae quick. Then a little flocculant to drop everything to the bottom, a good vacuuming, and your pool is nice again!

Works Great!

Worked for me...
Would Recommend(25,000 gallon pool) when nothing else was getting anywhere with my green swamp, and getting outrageous quotes from so-called "professionals" I decided what could it hurt to try this (it's not NEARLY as expensive as a lot of stuff I've bought to tackle this -that did not work- and I had to buy 2 of the Yellow Gone) - Chat GPT advised me well around the handling of this although the directions are fine - Chat GPT was adamant I follow the directions to a T. I did - I made sure the chemical readin...
The price is way high and I have an alternative
Would Not RecommendPlease do not but for less money you can buy the same from Rural king, The product is ammonium sulfate, a fertilizer available rural king 52 lb/ $20 or any ag store. Yellow gone infuses the product with copper sulfate hence the blue color. I get the same result from the cheap source. save your money or perhaps share the bags with neighbors
Yellow Gone - It Could Be Better
Would RecommendIt didn't seem to work completely. I still have issues with yellow algae that I'm tackling.
