Sump..no sump..dead sand..live sand..amonnia goesinta nitrite goesinta nitirate goesinta nitrogen goesinta big steel cylinders and sold by gas co..MY EARS ARE BLEEDING. I think my anurism has exploded!!!!! I do thank you all for you wisdom and the endless supply of knowledge I have recieved here, but will my head explode before I even put water in the tank????? 8O
