So, I recently decided to try real plants in the aquarium. This idea was a bad one, considering that I'm severely flora-challenged and I've never managed to keep a plant alive.
I bought a moss ball; I'm hoping I can keep him alive, at least...
But, I also bought an Amazon sword. I (stupidly) researched the plant after
I brought it home, and found that it needs iron to live. But, my water conditioner package says that it "removes heavy metals, such as iron, that may harm the fish".
How the heck am I supposed to feed this plant if iron is going to hurt the fish?
