I'll get some links up tomorrow afternoon.


Great. Post your tank parameters, if you know them. Size of tank, amount of
lighting, pH, KH, GH, temperature, nitrate reading, how often you do water
changes.

FWIW, it's probably not iron deficiency, if it's the old leaves being affected.
Have you see Chuck's page?
