A conversation between my wife and Candi got me thinking, will my floor be able to withstand a 90 gallon tank? We live on the 2nd floor of a 2 family house, the floor is hardwood, not sure how the beams run below us. The spot it's supposed to go held my 55 with about 80 lbs of live rock and 60 lbs live sand at one time and it was fine. Just kinda worried now that I've got the 90 and a sump. And now I'm thinking of downgrading :'(
