Bests & Worsts Reviews from Amazon

I had read through all the reviews and was worried if this would work, but I'd been staring and my greenish cloudy pool for 2-3 weeks and figured I needed to do something. I'm a new pool owner and read up on the various causes. All my chemicals were balanced and I was cleaning the filter weekly (sometimes more) to no avail. I finally decided to try this product and received same day shipping on 4/18. I didn't receive it until about 7pm so I decided to wait until the next day to watch the progress. I put in a little extra than what it called for, but not much. The directions call for 1 ounce per 5,000 gallons and I put about 4 1/2 ounces for my 17,500 gallon pool at aroun 8 am. I checked it at 9 am and there was no change. I checked again around 10 and I couldn't tell for sure if it was better. I felt like clarity had improved but wasn't sure if I was seeing things because I wanted so much for the cloudiness to go away. I checked again around noon and it was drastically better. I could finally see the drain at the bottom. I am so impressed and happy with this product!! I think my issue was excessive pollen that had made my pool cloudy and was too fine for the filter to catch. I plan to continue to use this routinely.
