Seachem Iron

[Jonathan Aquari]

Dose anyone dose Seachem's Flourish Iron. I dose the reg. Flourish but my swords are yellowing and I heard that means that i need iron. Question is, do you test the iron levles in your tank(s)? Another thing, dose anyone know of a Iron "root tab" or have use Takashi Amano's "Iron tabs"?

thanks

Hi all,
Yellowing leaves is much more likely to be a sign of lack of either nitrogen (N) or potassium (K) than of lack of Iron (Fe). You are adding micro-elements (like Fe), but plants need much higher levels of N and K, even than they do of the other macro-nutrient phosphorus (P), and an order of magnitude more N and K than they do for any of the micro-elements.
