Which brand test kit(s) do you use and why? Are they
accurate, easy to use,
reasonably priced?

I use Aquarium Pharmaceuticals for all tests. They're easy
to use, I suppose the price is ok (I don't worry too much
about that), and I'm assuming they're reasonably accurate.
mostly I like using the same test each time so comparisons
make sense. You can get different results from different
test kits.
