Earlier this year I had to drain my pool and 'acid' wash every inch of the walls and floor due to an algae overgrowth. I bought this product to use as the wash and it worked fantasticly well! I used a sprayer to apply it and scrubbed from top to bottom. It killed every bit of algae and left the inside of the pool bright and thoroughly clean. I refilled to pool and we are now enjoying a sparkling clean, healthy pool. Easy to use. Good value, great product. No leaking bottles. Highly recommended for acid washing.

OK, here's what I was up against. HUGE pool, 20 x 40 with a deep end of 11 feet. None of the equipment was working, it was a relatives hoarder house who passed away and we were left with the task of selling it. Pool was abandoned and had about 2 feet of green muck which the city finally red tagged. SO...I pumped it out, pressure blasted it, cleaned up and re-filled to pass city check. All fine, and the house sold...BUT within 3 days it was green. Even though the new owners were going to fill it in, the lender required the pool to be filled and clean. SO...(sorry for the long story) I dumped 4 gallons of this product in and swished it around with the net and brush. CRAZY but within a few hours it had started to clear up and next day...ALL CLEAR! Amazing since the pool equipment was dust. Probalby will need one more treatment before escrow closes. Very happy with this stuff.

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.

Purchased these as they have been commonly referred to as one of the better brands for liquid chlorine. we use this through the summer and also to regularly shock the pool and they are really effective. They're pricey but worth it. Easy to open and have the little foil inside so haven't had any leak issues.
