I had to SLAM my pool a few weeks ago, and bought gallons and gallons of bleach.
Chatted with my neighbors who are FBI (actually very high up the chain FBI, I’m in the DC area) about my use of bleach and laughed about them seeing my on a watch list.
No watch list for bleach, at least at the federal level. Buying Peroxide in bulk on the other hand will get you on a watch list. Who knew?
