My order must have had something spilled on it or something off because all the bags of shock we stuck together and the finish was coming off the bags- I let POOL SUPPLIES know and they are sending me a replacement order!!!! This is awesome and now what I expected. Great company and I will continue to use them for my pool needs!!!

What can I say? They are Pool chemicals that were delivered superfast the next day. I haven't used them yet because they were bought for the next Pool season.
