I like the pics very nice I now have some Ideas on the "carpet" situation. I want something as big as your "curtain" in the front and center of my tank. I might just try the poof method using a black lufa (sp?)
The reason I used the poof is because I didn't have any nylon hairnets available to me. Before I found the "poof method" I used sewing thread, which is still on some of the bigger pieces and hasn't deteriorated yet.
