What kit?
Taylor or Lamotte titration kits (drops) are OK. Some of the others -- not so much.
What you have to understand is that pool industry chemical sales DEPEND -- to the tune of $100,000,000's annually -- on inaccurate testing. And I mean that literally, not figuratively. If every pool owner had, and used, a K2006 appropriately, it would cost the pool chemical industry more than $500,000,000 each year. And again, I mean that literally; that is not an exaggerated number.
I'm not saying that everyone who contributes to bad testing is doing so maliciously, though some are. What I am saying is that accurate and valid water testing would seriously hurt EVERY pool chemical company and EVERY swimming pool dealer in the country. That kind of cuts down on their incentive to provide accurate testing, wouldn't you think?
When you add the fact that pool owners want, and ask for, easier testing methods, and the fact that they will spend money on 'cooler' test methods, like the expensive AND inaccurate electronic test strip readers, it's easy to see how the current situation developed.
NOBODY would prefer the K2006 to test strips IF the test strips were adequate. For a new pool owner, the K2006 is confusing and intimidating.
But, as Albert Einstein is reported to have said, we "try to make things as easy as possible . . . but no easier!".
The K2006 is not as easy as 90% of pool owners would like, but it IS as "easy as possible", given the need for relatively accurate testing.
