The surface feed into the filter unit removes fine waste materials produced by a marine aquarium
which may begin to form an unsightly surface scum. The surface overflow into the filter helps to
prevent water levels in the aquarium from dropping below a level that may harm any organisms
living in it.
2. Down flow and settlement Zone This chamber provides a perfect environment for the location
of a heaterstat, where the downward flow of water encourages an even distribution of water throughout
both the filter and aquarium.
3. Dark refugia When established, the dark refugia provides the optimum environment and large surface
for the nitrifying bacteria, and provides a specialist environment for the growth of a colony of light
sensitive organisms. Many of these organisms have evolved within the deep, dark crevices of coral reefs
where they have become extremely effective at consuming waste materials. Comparatively larger
particles of stone, ensure an even flow of water up through the chamber, enhancing the performance
of the entire filter and retaining larger particles of waste which are either consumed by the organisms
in the chamber or fall to the base of the chamber where they can be siphoned off.
4. Up flow light refugia The light refugia not only provides the large surface area required for an
effective nitrifying filter, but it also encourages extremely effective waste consuming organisms,
that have evolved within the upper levels of coral reefs, to settle here. By retaining this specialist
colony away from the inhabitants of the main aquarium, the diversity of organisms is enhanced
and the effectiveness of the chamber as a filter is increased.

Water is aerated as it cascades across a deflector into the downflow chamber and provides a
visual indicator of when the aquarium requires a top up. During the maturation phase of the
aquarium, when water quality may begin to deteriorate, the aquarist may use this chamber as
a highly effective traditional biological filter by using the fine foam filter provided and optional activated
carbon during the maturation phase. Once the aquarium has matured, it can then be
replaced by lava rock or live rock to increase the capacity of the refugia filter.
6. Downflow dark refugia
The dark refugia as the final chamber within the system provides the ideal environment for those
organisms that have evolved within the deep crevices of natural coral reef systems.
7. Circulation pumps
The pumps will provide the water circulation within the main aquarium to mimic the high flow
velocity and turbulence associated with natural coral reefs to provide optimum environmental
conditions.
8. Final chamber with protein skimmer
The skimmer removes the fine waste material that may otherwise lead to a decline in water clarity
and quality. The pump provided circulates approximately 1000 litres for optimum performance.
9. Skimmer collection cup
The skimmer will produce a brown watery substance that is collected within the collection cup.
The location of this cup enables the aquarist to remove, waste and replace it with ease.
10. Skimmer return
Water is aerated and returned to the aquarium.
