Our pool loves it!
Size: 4 Pack
We started getting this a couple months ago for the first time. We've ordered the 4 pack a few times now. It does a great job! Very happy with it! Keeps our pool looking, smelling, and "running" perfectly!! Recently we got a shipment in that there were only 3 gallons in the page. IT hadn't been tampered with. There was a day delay in receiving the item so maybe FedEx messed it up and changed it over to a new box? We dont know but the seller worked with us and is replacing the missing gallon. It didn't come in the white box packed inside the cardboard box so someone did something or forgot something. Regardless, it's corrected and we will get our missing gallon soon! The product and the sellers get 5 stars from us 😃

Happy with it
Size: 4 Pack
As expected. Pool chlorine. Seems the same as what I buy at my local pool and spa place but for a better price and it comes to my door.

One of the better brands available for liquid chlorine, our go to product
Size: 4 Pack
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.

Good
Size: 4 Pack
Good pool shock at a good price. People using this to wash their clothes thinking it is somehow less "destructive" than bleach: it's not. Pool shock is exactly the same as bleach, only twice as strong (12% vs 6%). So, it's actually more harsh on your clothes, not less.

Will Buy Again
Size: 4 Pack
Champion pool shock did exactly what it needed to do. It was a plus that we were able to buy in bulk. I feel like we are constantly buying pool chemicals and this was so quick and easy.

Easy and works
Size: 4 Pack
It works but I think powder does better. If you don’t want to mix then this is for you.

Wow! Just wow!
Size: 4 Pack
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.
