Adding floor support

I need to "beef up" the floor in my living room. The reason is due to a 280 gallon aquarium ( total weight will be around 3200 lbs. ) that will placed against an inside wall. Unfortunatly, the tank will run paralell to the floor joists. I can easily get under the crawl space to do this. One edge of the tank will be about 3 feet from the main beam, the other end will be about 4 feet from the outer edge of the house. My idea is to "sister" the floor joists ( they are 2x8 )directly under the tank as well as a few joists beyond in each direction ( maybe even tripling the joists ). I will also add vertical supports at 4 points. The vertical supports will either be 4x4's sitting on a concrete base, or those metel house jacks on a concrete base. The distance between floor and ground is about 3 feet.
Does this plan sound good or does anyone have a better idea? I also thought about using a steel floor joist.
Thanks for any advise!
