The one single piece of Advise I would give to new Aquarium builders would be to build a bathtub type of container under the Tank area large enough to contain all the water that could leak from a compromised Tank . I realize that you could not reasonably protect against some thing catastrophic . But you could against a slow but tank ending one. This would give you time to save your fish and Coral , rocks ect. If the situation allowed a drain off of this to a floor drain . If not a sump pump with float activation to some where . Especially in an Apartment where Liability is a concern . Then build a decorative surround making it invisible
