2 ?'s

#1 - Depends on what you mean -- CarlD made the name up to describe both the method I developed and the 'Bleach, borax, and baking soda' grocery store chemicals. Others tend to use it to refer to those chemicals specifically. I use it to refer to a general approach of using only what you need, from the most practical sources.

All of the elements of the BBB method, in the sense of referring to the use of those three chemicals, others did first. Combining them in the approach I did seems to have been a first. Someone *may* well have been doing all the same things, but they didn't ever publish it. And all the references I can find to the "BBB method" on the Internet seem to have originated here.

In the larger sense, of the BBB Method referring to my entire approach to pool care, there are some elements that seem to be unique. In particular, I was the first to identify aeration + lowered pH as the only effective method of reducing carbonate alkalinity in pools, and to point out that ALL the information the pool biz published on that point was incorrect. I've been told that people involved in industrial water treatment had been doing that for years, but again, no one in the pool industry seems to have recognized that. And, I've still never seen a published account of that, other than a user's post here, years ago, in which he said he'd been trained to do that.

If you're interested, the intro page to PoolSolutions lists some of the 'firsts' here. But please keep in mind that I consider it probable that someone else may have also discovered some -- or even all -- of these, and had been using them before I did. However, if they did so, they didn't publish it.

#2 It sounds like they may know what they are doing, as an organization. It's very common for service techs to have a wrong understanding of why they do what they do, but to STILL do the right thing. It wouldn't hurt to use a K2006 to check up on them periodically, but I don't know that it's essential. Still everybody works better if they know someone else is watching, even if it's in a friendly way.
