I'm currently planning on a 100 gallon marine tank and would like to build a stand for it without using a centre brace as this makes sump maintenance much easier. im think about doing 2x4 on the legs and 2x8 on the top and bottom.

Also how could I make the weight of the tank distribute evenly on the floor? The tank is on the first floor and the whole system will be 125 gallons so to stop any warping I'd like the pressure against the floor to be as minimal as possible so I want to increase the surface area between the tank and floor.

Any help would be appreciated!

What is the footprint size of the tank? Something like a 4'x2', 5'x2' or 6'x18" would have the 125 gallons sufficiently spread out. Not really cause for concern in damaging the floor imo. To be safe you can determine which way the floor joists run and arrange the tank perpendicular to them so the weight is supported by as many as possible. Also you could put it up against a load-bearing, usually exterior wall. But unless your tank is like a tall cylinder of 125 gallons then I wouldn't worry too much about warping the floor.

The tank is 5 foot x 2 foot so the footprint is a bit bigger than tanks this size I think. The tank will be on the first floor against a wall that is load bearing I'm pretty sure (has a steel beam running through it) and there is a load bearing wall to the right too. I'm not too worried about the weight, but I am trying to do everything possible to minimise it.

Just to clarify, would my wood sizes be ok?
