OUTSTANDING product. Highly recommend for multiple applications. I even use it for my pressure washing. Excellent cleaning and disinfecting all sorts of items. 12.5% chlorine is STONG so be careful. Mixes great. Wonderful pricing. (4) Single gallon delivery makes it simple to move around. Smells like any bleach.

Works great for my pool. Keeps my pool crystal clear. I pour a gallon a week close to the skimmer slowly. It keeps my chemicals in check, mixes immediately into pool. Perfect amount for my 24 x 54 above ground. I am very happy with this product. No damage to pool, like there was with powder shock. The package arrives sealed, and well packed.

This liquid chlorine pool shock is an effective way to raise chlorine levels fast and tackle cloudy water, algae, or routine pool maintenance. The 12.5% sodium hypochlorite concentration is strong and starts working quickly after application. I like that it is easy to pour and doesn't leave behind the additional stabilizers or calcium that some other chlorine products can add to the water. It's especially useful when a pool needs a quick chlorine boost or algae treatment. A reliable product to keep on hand for maintaining clear, clean pool water throughout the swimming season. 🏊♀️💦☀️

Use this for our well treatment facility. And it’s great and powerful. I sometimes use a splash to clean out troughs as well and it works excellently. It’s very strong and takes the algae away.

wow! Just wow! This is so insanely effective. I wish I had known about this years ago. I just sprayed my hot tub now and it instantly killed the algae and I was able to just hose it off. I recently used on a pool that had become a swamp. It killed off anything and cleared the pool in hours. But the most effective use is that it instantly kills mold and disinfects and whitens at the same time. I've never used a cleaner that was so effective. Somebody here was telling to use a spray bottle, a good quality, with half water, half of this product and some dish soap and I cannot tell you how life changing this mixture is. I'm somebody who easily gets grossed out so the fact that this neutralizes everything so quickly and it can just be wiped off is amazing.
