Really like the idea of the back wall panels. To me they look more natural after the Coralline Algae starts covering the back wall. IMHO I see so many good looking tanks that would look great if they didn't have the back glass/acrylic wall covered in Coralline Algae (It really hurts the infinite depth illusion). I know it is a lot more work keeping the back wall clean(another reason I am not a fan of Acrylic tanks,I'm glad you went glass) but it really helps the tank look so much more natural. With your good looking rock wall no such problems, plus less work and a more natural set up. Mike
