you just have to reinforce the joists measure the truss things from floor to the bottom then buy some 2x what ever the hight is and laminate on both sides of truss things. But remember truss structures are stronger than a single 2x8 would be they are designed to bear weight out word to the supporting ends. you may want to look into things a bit more you can probably do it with no troubles but check first, you may want to go to a 30g sump which is enough for a 90g.
