Works so well my daughters pool never looked so clear since she got the pool it’s the greatest product out there to use in your pool I recommend it highly

This has been the best product I have ever used in the eight years having this pool. I simply use this once a week and keep 3” chlorine tabs in my skimmer and I have had the best summer. I had 1 week of a small amount of algae growth after the hottest week of the summer. I simply doubled the amount I use each week and my water was right back to sparkling blue! I have spent a fortune in the past on several chemicals and waited weeks to see results not as good as this product.

This is the best product I have used on my 16x40 fiberglass pool. My pool builder recommends it. They recommended it so much that as long as I'm using it my warranty will stay 100% active.

Since purchasing a house with a 20k gallon pool in 2012, I’ve struggled with the pool’s PH and alkalinity. For persons with sensitive skin this chemical imbalance can cause skin irritation. A few years ago, a pool contractor recommended E-Z Pool to me, but I felt it was too expensive. At the beginning of the 2023 pool season, I decided to give it a try. The normal weekly dose for my pool is 4 scoops. For the first couple of weekly treatments, I used twice that amount. The initial results were ok, but there was only minimal improvement with the PH and alkalinity. On the third week I cut back to the normal dosage of 4 scoops, and the pool’s chemistry stayed flat. After about two months of using E-Z Pool, I put 27 lbs of baking soda in the pool. Within days I saw much improvement in the PH and alkalinity. When the PH and alkalinity levels began regressing, I started adding 7 lbs of baking soda with each weekly dose of E-Z Pool. The combination of the two have brought pool’s chemistry to near perfection. No more skin rashes! Also, I used to run my pump/filter for 8 hours per day. Now I’ve cut it back to 5 hours (savings). E-Z Pool has allowed me to cut my chlorine usage to half of what it was (another savings). By the way, next to water, baking soda is least expensive additive to my pool. Sam’s club sells 13.5 lb bags of Arm & Hammer for $8.66 each.

The product received was exactly as described! Got this for my mother because she lives at her pool all the time. She mention something about this. So got it for her as a surprise! She liked it, so much she called asking me to get her more. So I did exactly that!
