When setting up your reef, marine, or even brackish aquarium, was the weight that would be put onto your floor factored in?
I've seen many setups that are custom made and were additional support beams (if they inside of a wall, for example) have to be created due to the weight of the whole tank. In many cases I know that this is something that seems to be like any floor would support (if on the first level of a building, of course), but sometimes it can cause some heavy damage to tile or wood floors.
For example, the rough weight of a gallon of "aquarium water" (including the rough amount of gravel, decorations, and water weight) for 1 gallon can be anywhere from 10-14lbs dependent on what is in the aquarium. It might not seem like a lot of weight, but if you have a 55 gallon tank that ends up being roughly 550lbs - 770lbs just for the aquarium's inside weight (not including the stand, equipment, and empty tank weight).
