Hi Nanfa Gang!

While I was replacing my activated charcoal (carbon) I had a thought/question. I
am adding supplements to my tank as fertilizer for the plants which contain small
amounts of iron in the form of chelated iron.

Question: won't the charcoal absorb the iron and thus defeat the addition of the
iron. If not... then why?
