So the trend in bleach of revolving off-brands, lower concentrations, mystery ingredients. smaller containers, and higher prices continues. Submitted for your approval is "Moxie Outdoor Bleach" which I encountered at the Lowes pool section today. There is no indication of percentage on the bottle or website. I suspect it is 5% or perhaps lower. There was a new sign there saying 1 gallon equals two pucks. $4.95 per "gallon" (121 oz). I had to buy a few gallons because I'm out and Walmart has been bone dry all summer.
