I decided to make a 6' bubble wall across the back of my large tank. Have always had difficulty getting the bubble plates to stay down so I decided to epoxy them to 2" marble threshhold that I've used many times to finish the edge at doors to tiled bathrooms. I did it in two 3' (about) pieces with three Penplax gangable bubblers glued to each. It works perfectly.
