It is a fine kit but it is incomplete. The K-2006 is the one you want. The chlorine test is much better in the K-2006, otherwise they're the same. You are highly unlikely to find one in a store, and don;t let the salesman tell you the kits are the same.Is the Taylor k-2005 a good test kit to use?
Sounds like you had the 1004I have a K-2005 and it didn't come with CYA. It came with OTO, pH, TA. I had to add on CYA and FAS-DPD. Unless they've changed the kit...
