The Science of Refugiums

A refugium can be used for something as simple as just increasing your water volume or it can enhance your tank' performance and stability in many, many ways.

It is a miniature ecosystem attached to your main tank often housing isolated populations of sensitive animals or plants. Much like a greenhouse on a space ship, a refugium will improve the quality of your saltwater system by adding extra filtration, bio-nutrients and other food sources as well as giving refuge to sensitive species.

Refugiums can be used to keep the peace in your salt water tank: used as a refuge chamber for the more delicate species such as sea horses and peppermint shrimp (to name just two) who would otherwise become a food source for the other inhabitants of the tank. It can also provide a place to raise fry in a tank that shares the water with their birth tank

Refugiums can be used to supply live food and planktons to your aquarium. They are well suited to cultivate food sources such as algae and micro-fauna separate from the predation by herbivorous inhabitants of the main tank. Cultivating Caulerpa and other macroalgaes can help to consume ammonia/nitrates and phosphates that accumulate unhealthfully in your tank.

Refugiums can help maintain pH levels.
