I see all kinds of test kits, and from the stickies, I haven't found one that has all the tests inclusive in one kit. Am I looking right at one or what would be the kit recommended for a noobie to have? I am thinking of having a reef scenario in my tank, so I see calcium is high on the list.... Should I buy the tests individually to get the best test for each type of test? What would you long time reefers recommend? I have no problem with a link (or links) to a test kit....
