My dad won a brand new 150 gallon tank from a fish show about a year ago and hasn't set it up yet. He is concerned that he needs to reinforce the floor before he fills it with water. The tank will be in the same room with 3 other tanks, two 55 gallons and one 29 gallon. it will be on the first story of the house but the home has a raised foundation with post and beam construction. Do you guys with bigger tanks reinforce the floors and if so how did you do it?
