I am in the process of buying a new home and want to get a 360 gallon aquarium. The Home is a 1 level on a crawl space. In addition to this aquarium we will have a 120 gallon, an 80 gallon, and a 10 gallon. We will use a 55 gallon sump with the 360. I would guess that with water, stands, rocks, etc. total weight for the aquariums would be about 7000 lbs. I have not had a chance to get below the house too see the joists and such. I am not familiar with how the whole flooring works, though I have learned quite a bit over the last week of researching, so I don't know what to look for exactly when I do get to take a look, I am hoping that I can check it out this weekend. I am looking for any advice on what to check while I am below the house, and then what would be some good options to reinforce the floor to hold the weight. I am planning on putting all the tanks in the same room, except maybe the 10 gallon, so I will only have to worry about reinforcing the floors for the one room. Thank you for any help.
