Don't reuse soil.

They say adamantly to not re-use your soil. Anyone can argue that you can re-use soil. . . . . . but you're going to argue with those names? I'm going to say they're right. They say don't ever ever do it because of bugs, fungus and disease.
Try running an organic pesticide through the soil. Something garlic or neem based shouldn't damage your root system. I'd suggest visiting a growshop. . . . . but these bugs are either going to be eradicated by a $10-$20 bottle of insecticide or they are going to be a constant problem during your grow. If you can part with the seeds I'd toss it away.
If you want a good potting soil for way less than paying for ocean forest try this.
.3 soilless mix (pro-mix BX seems to be most commonly carried)
.3 compost
.15 perlite
.15 worm castings
.10 coco fiber
Add .5-1 cup dolomite lime per cubic foot of soil. Check out adding some azomite as well, its on ebay if not your local shop. Dolomite lime has a pH of 7 and pulls pH toward itself no matter what you do, it stabilizes the soil. Azomite contains all the trace elements you'll ever want. If your'e growing indoors make sure you get sterilized compost or leave the bag in the sun on a hot day all afternoon OR bake in the oven @ 150-200 degrees for 10 minutes. You're looking at making sure the compost reaches a temperature of 140 to kill eggs, pests and fungus.
Good luck man
