Will do later tonight. I did not seal anything. There is actually a 1/8" gap in between the tubs and the next shelf so it is making holding humidity real fun right now since it is so dry out. I am having to mist 1-2 times daily. One time for my normal tubs and twice for the tubs with shedding snakes. I am using a footlong strip of 11" flexwatt under each tub and each piece is taped to the shelf. I made the gap so I would have room for the tubs to slide over the flexwatt with no problems.
