well I have looked at your tank thread here, and the plants you are getting from me will LOOK GREAT in this tank . I LOVE YOUR BACK WALL and want to do the same in my 20 tall, or maybye a 10 gallon to start with , awesome job !!!! you can lower the water line, dry a rock or 2, and super glue anabuis to the rocks, or like you said java moss, in a few places I would only put a small amount in the top right corner, that way if it becomes a algea trap you could tear it down without having a mess of glue showing , you only need a dap' . I will sell you 2 small anabuis so you will have these to go on this wall . and the big ones you are buying will look awesome as a background here !! maybye one in the front right corner, as far as the front left corner I think microsword will LOOK great in that front left corner, It will take a little while to grow into the sand, but just add a few of your rocks, (2) on the top, and move them around every so often as to not let any of it die off, it will root in well in no time !! I think a 6X6 would cover a LARGE amount !!! you could even cover the whole front area !!!! foreground part . I cant wait to make me a background like this, and for the algea, your algea eaters should work, but tell you what Buy 2 nerites from me atleast 2, if not more, and YOU will see the HUGE differance they slide over the lagea and eat it ALL up !! I have watched them take a log driftwood I placed in a tank covered in brown & lots of green spot , and they cleaned it spanking NEW in 2 DAYS !!!! they are a must have for a planted tank . they DO not reproduce in freshwater, so you just buy however many you need. I am seeling them now for 2 bucks !! and I can easily add them in your order 
your tank will look amazing after you get my package, I cant wait to see pics with ALL the plants going in !!!!! I am sending you another PM now !!! ~~~~~~~~~
