thank you both for your input.
Right now, I've started with seachem trace and placed a root tab for the sword (about 4" from the roots). It's funny that you suggest water wisteria, because that was my 1st thought. If this turns out to be a mess, That's my plan B. Thank you for the link suggestions and book suggestion. I would like to read up on what I'm doing instead of just surfing youtube channels and reading stuff online.
