Great item does a great job keeping my pool cleaned and chemicals balanced

Great product and great fast shipping.

I have tried everything to keep my pond, clean, free of algae and slimy water. In the last month I’ve probably spent close to.$150.00 on different products to try to shock my pond . I finally got desperate and thought about cleaning pools.. I tried this product and it worked fantasticly Instantly my water was clear all the green and white stringy debris was clear from the pond it looks just beautiful.. one note…. it comes in 2 gallon jugs inside one heavy box. The only downfall was, it was too heavy for me to lift had to get help. Good price excellent product I recommend it highly.

Cleaned up the pool in no time

My pool guy recommended this exact stuff. It does the job to keep my inground pool clean and safe! It is the best stuff around at a reasonable price too.

This is the most ineffective liquid chlorine I have ever used. We have owned our pool for over 30 years and have used many different brands of liquid chlorine with good results. This brand, although it says 12.5 strength is not!! Thetest strip right in the full strength shows no chlorine.....no reading.....it has no active ingredient!!Not sure what is wrong but I won't be buying this brand again.
