You don't the want high amounts of oxygen in the substrate that an undergravel filter would cause. Plants via roots transport small amounts of oxygen down into the substrate. Plants also create a very slow flow of water by a process known as guttation. So put lots more plants and pick up a good aquatic plant book or search the web for articles detailing the physical and chemical processes taking place within the planted tank substrate to fully understand what's going on.
Remember this. This is a planted tank with fish, not a fish tank with plants. They bear only a superficial appearance to each other but are really two entirely different things.
