This is all I can find at Kroger this morning. It says it is 7.13% chlorine (never heard of this percentage but whatever). The “concentrated” part is what worries me. Everything else is just regular plain bleach. I only bought 1 bottle since I am unsure and wanted advice before buying more possibly. If it’s a no-go for the pool I figured I’d just use it for laundry. ?? This is the ONLY bleach they have in stock that isn’t scented or “splash-free”. What are the effects of using “concentrated” bleach? Fortunately, I still have 6 and a half gallons of 10% LC left but I picked one of these up to find out if it can be used. If it can, I’ll go buy more before they’re gone (like all bleach lately). Sorry if this is a dumb question lol. Thanks in advance!
