As always Don very cool. Im gonna be working on my 20 gallon End View today so I'll also be posting some pics. I like how you use cork rounds in your tanks. I don't think I could use them is this tank but Im picking up another 18 cube today so I'm definately going to use them in that one. I can call it my Don copy. what other kind of wood do you have in there? Where did you find it? It looks different?
