Get the OTO, so you can have some reliable, if not super accurate, testing now. Later, the OTO will allow you to do very quick and easy testing (almost strip-like) in between K2006 full testing.

Oh. And don't over-test CYA: the K2006 is sort of short on CYA tests. This isn't a problem for experienced users, since they know CYA doesn't change rapidly or need to be tested every time. But new users sometimes blow through all the CYA tests in their first month, and have to buy refills.

I have not tested CYA yet, but i will this weekend or tonight. The privious owner was using chlorine tabs so im sure it has some CYA in it.

So which kit the K-1000 or the K-1003
