Hi DC;

You're exactly right about what it takes: "it's almost like holding your breath and trying not to sneeze" is a GREAT description of it.

The problem is that a LOT of the folk here were in a hurry before they got here, and in even more of a hurry by the time they decide to look into something as strange as a "BBB method". Just to get them to slow down, test their pool, stop adding goo, and clean their filters is as much as we can do. Trying to get them to spend several hours (depending on vacuum head, suction, and so on) slowly and meticulously vacuuming their pool is just a recipe for disaster.

I constantly cut and trim things toward my thumb; I don't recall ever cutting myself that way. But I NEVER teach my Scouts to cut that way!
