Do I Need A Refugium For My Saltwater Aquarium | Aquarium Fish ...

With the refugium light on at night, the plants you have in your refugium will use the CO2, make oxygen and stabilize the pH. Another benefit for having a refugium is that since it is a little environment separate from your display aquarium you... The other advantage to having a refugium is that the lighting you put in will be on the opposite cycle as the light in your main aquarium, this will help stabilize the oxygen and pH levels in your aquarium. For the Aquarist, refugium means a refuge that shares the same water as the display aquarium but is isolated from the rest of the aquarium. These can be netted to supply a food source for your fish or they can migrate naturally to the display tank via the connection lines. Having a refugium as part of your display aquarium provides many benefits for you and your fish. Besides sand, micro algae and crustaceans, you will also want to put in your refugium aquatic life that will not do well in the company of more aggressive fish. For this reason predator fish should not be placed in a refugium or they will eat your entire food source. By reducing these contaminants from your aquarium, you will help eliminate the growth of unwanted algae in your tank. You can choose from those that hang from the side into the tank, stand-alone, built-in or even internal refugium. Many Aquarists will put in such aquatic life as seahorses, some shrimp and small fish. The macro algae and sand that is in your refugium will become natural filters for your display aquarium by reducing phosphates and nitrates. A well-designed refugium provides many advantages for your main aquarium.
