From an
overflow system in the tank water can flow down into the sump tank.
The water will run into a pre-filter pad that filters out debris,
and subsequently flow down to the wet-dry filter (Bio-Balls)
Inside a
standard wet-dry filter, we can find various bio-media, for example,
bio-balls. Bacteria will somehow, stick themselves to the surface of
the bio-balls while at the same time, smoothens the airflow
Oxygen(O2)
into the media. As more oxygen gets into the media, the bacteria
combines with it and gets the resistant to oxidize waste materials.
Generally speaking, extremely harmful Ammonias (NH4) and Nitrites
(NO2) will be oxidize into not so harmful form of Nitrate (NO3). The
Ceramic rings or SeaChem De*nitrate will be able to
create a process call de-nitrification
which would change Nitrate (NO3)
to Nitrogen Gas (N2).
Additional
help in the filtration process will come in the form of a protein
skimmer or a foam-fractionator. A large circulation process will
happen, which is resulted by a heavy jet of water that is created by
the protein skimmer. This will remove organics, fats and protein in
the water, which in turns, lessening the oxidizing process in the
wet-dry filter.
A
layer of sand 1 inch deep and 2 inch of
gravel on top of it, will be placed at the bottom of the
tank. This gives the feeling of a real ocean floor. Live rocks will
also be placed on the sand, which in-turn, forms the foundation for
the living corals that gives the finishing touches of a true marine
environment.
