Clorox Pool&Spa Shock Xtra Blue Pool Shock for Swimming Pools

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 ...

Best price in the area. Product works great. Use at the first sign of algae and it does as promised - kills it and makes the water a beautiful blue.

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.
