Oh Vicki it looks fantastic! I think that will look stunning when planted! Thanks for letting me know what eggcrate is and why it's used, I don't use many rocks, but it's good to know for the future! The one large rock I do have in the 30 makes me slightly nervous, i might think about getting some eggcrate when I move the tank.
Also on a bit of a sidenote, I really like the color of your tank stand
