I just purchased a new 55 gallon aquarium at the pet store near my parents place in Pennsylvania, because it was cheaper. I need to carry it 90 miles back home. Currently it is on the back seat of my car with the seatbelts wrapped around it so it won't fall off the seat. I'm wondering if I should do anything else to protect it on the drive, to prevent it from forming leaks. Most of the weight is on the ends because the back seat isn't flat. The tank is empty, aside from the hood, which is sitting on the bottom. I'm not sure how much stress it is designed to handle. Does anyone have an idea of how much stress it can handle, and what I should do to protect it?
