I use one to track my Tropica MasterGrow additions.

I agree. I try to keep my iron at 0 (<25ppb). I try to add a dose of TMG
and then wait till the tank has reached 0 for a couple of days, then dose
again. If you try to maintain 150 ppb with TMG you will end up with too
much iron in the water and algae. Heck I have a little algae even with the
low iron I use. The Sera kit is to keep track of the Fe level. I usually
check about 3 days after a dose, it shows a trace (say 50 ppb), I wait 3
days and dose again. Same regime for N, I have almost no fish. But I
redose when the N falls to 1ppm or less.
