FWIW, I've never seen liquid chlorine locally at any of the stores y'all can get it at, nor is it available now. I could probably get it at a pool/spa store. I may call around tomorrow. I bet it won't be cheap. I don't mind using bleach, but I'd love to try a higher concentrate. Just for fun. I just can't get it here like other places.
We're just not very swimmy I guess. This summer, being the coolest/cloudiest in at least 7 or 8 years. If not longer. And me with my CYA at 50ppm (insert idiot measurer - me), instead of the 20-30 I normally do, in much hotter summers. Due to cloud cover that I thought was real. haha
I get the feeling that Walmart might have brought some in when they promoted pools earlier this spring, but likely didn't keep it on the shelf long if they did. We only got Walmart like 20 years ago. I know Fred Meyer didn't jump on that bandwagon (our local "Walmart" before Walmart was a thing), and I've never seen it at Home Depot either.
Y'all are lucky to be able to find it. If I could I'd go get me some of that last stock.
Elsewise I'm doing 6% at $1.49 a small bottle I haven't even looked at ounces yet. My pool costs about $4/week in bleach.
