Clorox Pool&Spa Shock Xtra Blue, 12 lbs

from Robin

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 ...

This is the Best shock that I have found, after trying a bunch of others. It works wonders on our spa. Don't waste your time with any other brands of shock.

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.

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

I have used this product for a few years now and have never had an issue with algae. For the most part I use the BBB method of pool sanitization and use this Clorox product as my shock.
