1. Fit refugium securely to outer-side of the Aquarium or sump, using screws (supplied) to do so.
2. Place supply pump to inside (in water) of aquarium/ sump close to the refugium.
3. Secure pipe work (12/13mm) to outlet of pump and run the pipe work to inlet of refugium (12mm). Check spray bar is secure.
4. Add the 90o elbow and tubing if required to aid silent running. Gluing into place maybe required.
5. Add mineral mud to the refugium and lay the sand directly on top of the mud.
6. Look over all fittings fitted to the refugium and start pump supply to the refugium.
7. Add power to pump and water should start to flow into the refugium. Allow to fill.
8. The water flow should then exit the refugium via the outlet. Add elbow and silent tube to the exit if required.
9. Add lighting unit the lip of refuge, using either the internal or outer lips… whichever suits your setup best.
10. Check running after a few hours to make sure everything is running as it should.
11. After a period of 4 days, the refugium should be up and running nicely. Add inhabitants and caulerpa to the refugium as required.
12. Periodically check the flow through the unit and remove blockages etc where necessary.
This system is a natural filtration system that simulates the environment found in coral reefs.
You do not need a protein skimmer although if you are using one at present you are advised to run it for an hour approximately twice a day until the filter has begun maturing.
The water is kept well oxygenated through the photosynthesis of caulerpa eliminating the need for air pumps.
Run the lamp 24 hours a day causing the caulerpa to grow only through photosynthesis. The caulerpa will prevent the unwanted growth of hair algae within the main tank by competing for the essential nutrients.
The growth of the caulerpa can be controlled by harvesting it with scissors to use as a fresh natural food for your fish.
Fishes living in a system operating with a well established refugium remain much healthier and more colourful. Research has shown that this natural filtering helps prevent and can even cure Lateral Line Disease. This is the most cost effective way to keep your tank perfect.
