[APD] RE: Test kits
Speaking of test kits, I need a good Iron test kit within a reasonable
budget range. Right now I have an Iron test kit from (I believe)
Aquarium Pharamceuticals. The test is incredibly hard to read for me,
the difference from 0 to 0.1ppm would probably be pretty damn close to
impossible for me to tell. Can anyone recommend a good Fe test kit
(within a reasonable price, $70 listed at Tom's suggested sight is _way_
too much for me ;-)?
Seachem's Fe kit works reasonably well and is inexpensive. It also comes
with a reference solution which is very useful for testing the test kit. I
find the color comparison to be a bit troublesome (I'm not a big fan of
that type of test in general), but it has a large color strip that is
spread out enough that you can get a decent reading from it.
What I would *love* to see is some actual spectral absorption/transmission
plots for these types of test kits published by the manufacturers to allow
DIY and 3rd party electronic readers for the color-change type tests (hint,
hint Seachem ;-).
