Micro swords will require strong lights @3wpg to keep low, and, if you do get them, you will want to almost plant them in individual strands about a blades width apart, or they will most likely develop algae in between them.
Most carpeting style plants are best planted with a lot of patience...
I had some micros in my main tank, but is now in what I have deemed my algae recovery tank. I pulled all the micro swords and bleach dipped them because of the algae. It is recovering nicely at the moment.
Have some dwarf hairgrass now, but also have two pots of glosso I think I am going to put in tomorrow on water change. Need lots of patience to do glosso the way I like it too look.
