I find it both sad and hilarious that a pool store wouldn't see you a K-2006 even at an inflated price. I'm guessing they want you to use one of the junkier kits and have to come them for proper readings. Inane. Like a tool store recommending you buy a bargain brand hammer rather than an Estwing. That fact that they stock the K-2006 is pretty amazing but if they stock them for the pros I'm surprised they don't stock the K-2006C instead.

Just yesterday I had to buy some CYA at a local store and the young saleswoman tried to tell me the alkalinity raiser was a "special" formulation of Baking Soda, as if it wasn't NaHCO3! "Yeah, right. I just need the CYA."
