I'm glad to be back into the hobby and I am purchasing a 90 gallon tank. I live in a mobile home and it doesn't sit on the floor therefore I am curious to know if any other members live in one and don't have a problem with heavy weight. The biggest I've had was a 55 gallon but I'm sure 90 gallons is a lot more heavier. Regardless I will get some 2x4s and reinforce bottom of the area where I will be setting up my tank just wanted to hear any other experiences
