i am trying making a false bottom for a 28g bowfront. i have a couple of questions. i want to make a little pond and water fall. first how high should the false bottom be? and how do i add a pond? i will give you a run down of what i am doing just to make sure i understand correctly. first i am useing pvc pipe to hold up the eggcreate. now if their is water under the entire false bottom then how do i make a pond? i want the pond to use the water that is under the bottom cause it will be filtered but how do i make a pond?
