I use Vision Cages that also have sliding glass doors in tracks. Can you remove the doors on your tanks? I don't use loose substrate but at times the tracks do get dirty. I remove the doors and clean out the tracks with a paper towel moistened with virosan. A thin knife or screwdriver is useful at times to move debris in the track to one end and then to lift them out. Also with loose substrate a small, powerful vacuum will work also. Bill
