depends on the span of the floor joist. Also, to a lesser degree, depends on the local design codes.

How big is your room and is the tank going against a wall?

the joist can span whatever i need it to. if i need sills placed every 4 feet so my span is only 4 feet that is what i will put, if i can get away with 15 feet then i will do that. i will build whatever i need to get the job done, i am planing on double 2x10 ever12 inches(floorjoists), then for my sills whatever you think would be the best, if i have to tripple up the joists i can do that to,

thanks for the help

I didn't spend a great deal of time but I think you can get by with double 2x10 spaced about 16" apart on a span of around 8 feet.

I assumed this tank will be near a wall and that the joists are perpendicular to the tank.

not a load bearing wall, this should not matter as long as the sills are placed at the right distanse under the tank, write or wrong

right. what I was trying to say is that I assumed the tank is not in the middle of the span but near one of the sills

Are you going to build the stand yourself?

What I did on my pier and beam for my 375 g:

I used 4x4 posts that went straight down to the ground on top of concrete footings. This way there is no weight on the floor, it goes directly to the ground.
