Swords Need Iron?

Hello Everyone!

I recently acquired a new sword plant and keep reading they need very iron-rich substrate. How important is iron for sword plants? Does anyone have any recommendations for supplementing? The sword in question was originally grown half-submerged in a red-clay type soil mix (which I assume is rich in iron).

My tank is low-tech, (very) lightly planted and the substrate is just small inert pea gravel. Already in the tank is some parrot feather (that's been taking over), some hair-grass I put in about a month ago that is just starting to show new growth, and a clump of moss that just sits in the corner and doesn't do anything.

Thoughts? Opinions?
Thanks in advance! Any advice will be appreciated!

Swords really do need more than just gravel to survive. I've tried many times in the past to grow them in gravel only and the swordplants just limp along for a year and eventually die.

Buy some iron tabs and push them into the roots. Once swords get going, they are an amazing plant.

Thanks for the replies.

For now I'll try some root tabs, but I could be persuaded to try a different substrate, (I was looking for a good excuse to set up a new tank anyway:)
Recommendations for someone who's never used anything other than gravel before? Something that won't affect pH?

I've used different kinds of root tabs and have never had any problems with them altering my pH.
