My local pool store has this test kit at what looks to be a good price - less than half of the best internet price for the 2006. It look to me to be the same kit as the recommended 2006, except that it doesn't include the CYA and CH tests. Is this the case ? If it is, I assume I can purchase the reagents for these tests and add them to the kit, or rely on the store for those tests. Any thoughts ?
