czcz said:Someone please correct me, but its possible to test available (ferrous) Fe with a color indicator using KSCN, or to percipitate the ferric iron with a hydroxide (to make Fe(OH)3). If I test at a lab I'll use these experiments from my old lab/chem books.
I think for our purposes we'll just need to use plants as Fe indicators in our tanks, limiting trace dosing to once a week for a couple weeks, then report back. Something like Wisteria.
Thanks guys.
czcz said:I can test at 2dKH. How often are you dosing traces, Bill?

Thanks 7Enigma and Jchillin.
