We do have access to Sam's, but it will be a couple days before we can get up there. The Chlorine and Shock that we have from Wally are both 47.6% calcium hypochlorite
I'm not sure if I saw a different bucket test or just didn't read it right; as I was filling the pool I put 3 gallons of water in a bucket with a 1/4 cup of bleach and it stayed clear for over 24 hours, I'll have to do the other way as well.
We just got out of the pool and noticed the floor and walls feel a little slimy.
Would some water softener salt dissolved in a bucket then added to the pool water help?
