Ok so I have a couple options for getting some bleach.
Option 1 2.5 gallon jerry jugs of bleach 12.5% for $10.95 each. I asked and the bleach was made a week ago. They make their own bleach on site.
Option 2: Go to Ocean state Job Lot and buy the 4 gallon case at $12.00 also 12.5% Just not sure when made etc.
Opening the pool so will be doing the SLAM process.
Thanks in advance for any and all advice.
