We need replays to give proper advice. If you want to go a bio based style you need to be very active on the map. You want to engage their tanks before they get right outside your base. If they do get up to your base you will have a very hard time because you need to pre split your bio army a lot into a large concave (much like zerg do) and you won't have room to do this.
