A false bottom ia a raised platform made out of light diffuser panel (egg crate)and PVC sections. Then screen is placed over that, then terra-lite/Hydroton, then screen/landscape barrier, then soil. it allows for a deeper water table (keep water at least 1/2 inch below false bottom) and room for plumbing like pump or filter. A simple drainage layer of gravel Or the more prefered Terra-lite or Hydroton is when you place several inches of the afore mentioned items in the bottom of the tank cover with screen/landscape barrier and then your substrate. I like this way myself. you can make streams or ponds by dimpling the areas you want to have exposed water and lining with rocks and such to form natural looking water beds. also you can make a chamber separate from the main area that you can use for a pump or filter. just keep the water level 1/2 inch below the substrate so you dont end up with a bog. when the water gets too deep just suck it out with a baster of something. I hope I havent confused the matter further.
