I have a couple live plants, java moss, blansea (I think that's what it is), and valisneria spiralis. The Spiralis is a pretty new. It doesn't seem to be growing and it has lost a couple leaves. I was wondering if it needs iron. I don't give my live plants anything (no Co2 or fertilizers Etc.). Would it be a good idea to get some iron supplements? My blansea is doing GREAT! I have had it for over 2 years. If I do need to get iron, what do I get? Any better brands or anything?? I have NO experience in this area. Are there any household products I could use instead or anything like that? Thanks!
