I'm at Leslie's buying some liquid CYA and about to do a SLAM so I ask the pool guy "Do you have any liquid chlorine?"
Pool guy - "NO! That is illegal!"
Me - Really? I can buy a truckload of it next door at WalMart, it's called bleach.
Pool guy - "Oh no that is BLEACH not liquid chlorine. Liquid chlorine is banned and illegal in all 50 states!"
