Even though this is not my first tank, I still messed up by putting too much GS and I had to cut a lot of it off. Can I just glue the dirt on and not worry about all the spongy foam not being sealed all the way? I was planning on using wood glue/titebond to add the peat moss. Or should I seal with silicone first and then add the dirt? Or am I screwed and need to start all over. There will be no water feature in this tank. It is a 20 gallon high. Here are some pics.
