Looks great. I love the layout, very peaceful, especially with the round river rocks or whatever you call them. Makes me seriously want to de-rim my 29, I have de-rimmed two 20 longs but the age of my tank and the room it is in concerns me too much to take any change, even though I feel like it is perfectly safe. Nice work.
I am really liking the layout with all the rocks too. I ended up making the 29 rimless because the rim was kind of lopsided or warped but it ended up looking awesome.
