Shockingly Automagical

After a long Maine Winter with special squirrel tree rat thanks to Puxatawney Phil (the glorified woodchuck), my pool was a pea-soup pine pollen swamp. Poured this magic in and I could see the difference inside the first twenty (20) minutes!

Love it! We have a 16x48 above ground pool. I just add 150ml once a week as well as replacing the chlorine tablet. I haven't had to add any other chemicals. Pool doesn't smell so much like chlorine compared to when it used to when adding other Clorox pool shock. We will continue to buy this and it came with 2 big gallons, I believe that will last for the whole summer and more😊
