Living in an appartment is a tricky situation,,,You must realise that this is not your building...So anything that happens below,or around your appartment WILL be the aquariums falt..(I have a crack in my wall,my cealing is leaking,my toilet wont flush,,It must be that aquarium)Sounds crazy,but I bet it will happen...You would be better off in the long run to have a smaller tank till your living conditions are a bit more permanent.
