Clorox Pool&Spa Shock XtraBlue Shock Pool Chemical Type Form for Swimming Pools

Works very well and keeps are pool crystal clear. When I first started putting it in our pool, put 2 bags the first week and now just one bag every week and it works perfectly. Have tried other products but this is definitely the best we have ever used.

Works great in my pool. Its my go to brand and I dont trust any other brand. I stick to what I no works.. its a great value for the money. I have no conplaints. Melts away fast within 15 mins and Im ready to swim. It dosent clog my pool in my pool or my pool pump. Keeps my pool cristal clear all summer long, I shock my pool at least wver two weeks or sooner if we have heavy rain fall. I also use it along with Clorox pool chlorine.

This pool shock works great... keeps my water crystal clear.

I have a 15 ft 32" inch Easy up pool and kids ...I put this in once a week because with all the kids germs and with the 104°F heat the algae builds up.. so soon as it start feeling slimy I put 1/4 cup of this in the pool and it takes care of all the sliminess even the filter looks good after using this .you only need about one fourth cup one bottle of this will last you two months... Or longer for an easy up pool

After a hard rain and us not being in our pool for a week the chemicals got away from me and our pool was green. used 3lbs of shock (1lb every 10hrs or so)and some algaecide and in about 36hrs our pool was back to blue! 1st photo was 12hrs after 1lb of shock and it didn't do much of anything. So I put in another 1lb and about 5hrs later was the middle photo. Then that same night I threw another 1lb in and the next morning (12hrs later) is the last photo.

I've used Clorox Blue Xtra shock for 3 years or so. It seems to work better than standard shock and I've only bought this pool shock for a few years now. No more opaque green pool water!

Great product.Ga heat makes the water turn quickly but this is a good solution. I have an 18x48 pool Used 3 bags to make it clear. Pictures are a day apart.

Excellent product, Crystal clear water

We've used this in the past for cloudy water, maintenance, and to rid the pool of developing algae. This year, with all the rain the pool got away from us and algae had begun to develop to a neon green color. We vacuumed the pool to waste, added extra chlorine, and dumped a bottle of this in, then ran the pump for 8 full hours. The next morning the pool was sparkling blue. Worked great for us.

this product is awful! it will not keep your pool from turning green. and when you do get your water back , it looks thick. cloudy some might say. if you want to battle your pool instead of enjoy it, then this is what you want to buy. otherwise, dont! walmart needs to bring aquachem back! now that is a product that works. i found aquachem at another store, bought that 5 pack for $14.99 ( way cheaper than this stuff) put 2 bags in and poof!!!! swimable pool! i would have given 0 stars but wouldnt let me. the first picture is after weeks of fighting to get pool right! the 2nd picture is after just 2 bags of aquachem
