I am having a difficult time getting liquid chlorine in Houston this summer. I am guessing supply chain problems with COVID-19. Anyway, my go to source has always been Home Depot, which typically has plentiful amounts of very fresh, 10% LC. Except this summer. We have a newly opened Pinch-a-Penny nearby, and they have 10.5% LC stored in a large tank behind the shop. The price is pretty equivalent, after you pay approx $15 for the refillable storage container. My question is...how potent is that LC coming out of a tank sitting in the hot Houston sun? This is a new store, so I have no idea how often that tank gets filled. Is there any temperature protection built into a large storage tank like these stores have? Or is it just the same as me storing a one gallon jug outside in 95 degree heat? (I don't do that, BTW.)
