I'd like to advise u to use finer gravel as because u are having plants that grow complex root systems. The coarse gravel will damage their roots.
I have been wanting to do that actually. I wasn't planning on a planted tank when I initially set it up, and jumped into the plant aspect with a little too much excitement lol. Gonna get my 5.5 set up so the fish I hav will have a place to live while I rescape this one.
