Fool Store

Higher concentrations of liquid chlorine seem to lose their potency faster than lower ones. So, they are probably not diluting it but it is just degrading. The turnover and sell rate for Walmart bleach is quick so more likely to be fresh.

Glad you are learning here and enjoying the forum!

(BTW, I like your new term --- "Fool Store." )

Yes, I considered that lesser inventory turnover rates leading to degrading potency might be blame. I just didn't think it would have such a large effect. The FC jumped to 10.5 with the 8.25% Clorox brand when I was expecting about 4 ish.

I was "pool-stored" when we first bought our house with a pool. As first-time owners, we didn't know any better ...after much online research I stumbled upon this forum (LIFESAVER!). I tell everyone I know about it and encourage them to get the right test kit through the site. A Leslie's store opened up around the corner from our house, which was terribly convenient, so I hesitantly went in to purchase the liquid chlorine (10%) and equipment I needed to replace. When they asked about my maintenance methods, I point-blank told them I used the BBB method, that it had worked for me for years, and I wouldn't consider trying anything else. Rather than try to sell me chemicals I didn't need, they actually wrote down the name of the forum and now recommend it to their customers! I was surprised that they would, but I've seen/heard them do it while I was in the store! A very pleasant surprise, and great for the customers they service

Must be something in the water down in TX

Let's hope it spreads (before they replace that crew).
