Re: Test Kits - which ones are necissary None of them are necessary, but many can be useful. I like to have GH, KH, pH, NO3, NO2 and NH4 around. These tests are all available at affordable prices, and tend to serve well enough to aid in diagnosing a number of major problems, or performing some general tests. Calibrating them helps.
I find most other tests to have ambiguous accuracy; there are Fe tests that didn't show iron when I tried to calibrate them, despite the massive presence of iron. I personally haven't found PO4 tests to hold enough accuracy for my purposes, or are distinguishable enough to tell the difference given the parameters that my dosing keeps the column within. K+ tests are a good joke. Cl+ tests shouldn't be necessary most of the time, and I have no experience with them.
Of course all of this changes when you shell out for a very high end titration test kit that'll cost you $300+ for the master kit.
