Question Question: Iron Levels ???

I have a quick question. When reading plant profiles, I tends to see descriptions that outline Nitrate and Phosphate levels in ppm though most plant profiles describe the Iron dosing in terms such as light, dose, heavy, or double without reference to a numeric value. Nutrafin Fe Test (Free Iron & Chelated Iron) measures Fe within the range of 0.0 and 1.0 mg/l (ppm) and suggest the following guidelines:
  • Free Iron (Fe)
    • 0.0-0.1 mg/l = Ideal level
    • > 0.1 mg/l = Partial Water Change or Chelate Iron w/H2O Conditioner
  • Chelated Iron
    • 0.0-0.25 mg/l = Iron level is low
    • 0.25-0.5 mg/ = Ideal level of iron in water
    • 0.5-1.0 mg/l = Too much iron is present - perform water change.
In the planted tank world... what do the relative terms - light, ideal, heavy, and double mean in these terms? Similarly, what is too much? Thanks, in advance,

When it comes to ferts and "too much", I wouldn't think too much about it. The recommended range for Fe is 0.10 from Seachem. I dose 10x that amount because I have, what I beleive, are iron hogs. I really don't know because I don't test. I do know that my plants look happy and healthy.

All I do know is, I can add plenty with no ill effects. That goes for all ferts.

Try to teach your brain to concentrate more on lights and co2 and not worry about the ferts too much.

Read the sticky here and you can see the levels most folks are dosing.
