SAFETY:
1. Turn off all switches and unplug all power
cords from outlet or power source before
performing maintenance.
Refugium Setup With Refugium
Light (not included)
1. Remove left and right filtration covers.
2. Remove overflow tray and filter cartrige
from center filter chamber.
3. Once the BioCube aquarium is fully set
up and ready to support livestock, add
substrate and macroalgae to the refugium
chamber. Replace overflow tray, filter
cartridge and left and right filtration covers.
Refugium Light Installation
(Figure C7)
1. Locate window on the back of the BioCube HQI.
2. Clean area around the illumination window
with a dry cloth to remove any dust,
salt or water.
3. Follow instructions included with the
refugium light to mount to BioCube HQI.

FIGURE C7
BioCube Filtration Stages
(Figures C8–C10)
1. Water flows from aquarium into the surface
and bottom intakes into chamber 1 where
some enters the protein skimmer
(Figure C8). The protein skimmer removes
many harmful organic materials from
the water.
2. From chamber 1, water flows over the top
of and through the filter cartridge into
the refugium in chamber 2 (Figure C9).
Live macroalgae and live rock in the
refugium remove excess nutrients and add
oxygen to the water while helping stabilize
the pH level.
3. From the refugium, water flows into
chamber 3 through the sponge filter
and into the water pump (Figure C10).
The water pump then forces the water
through the flexible tubing and back into
the aquarium through the discharge nozzle.
