Among reefkeepers, the term "refugium" refers to a lighted tank or compartment, separated from the main display tank, well stocked with macroalgae and beneficial invertebrates and devoid of predators that bite, crush or sting.
Adding a refugium to your reef tank system is a great way to help maintain favorable seawater quality while at the same time providing a "safe haven" where a variety of beneficial planktonic species and bottom-dwelling micro-invertebrates may reside and multiply. The dominance of autotrophic, photosynthetic, oxygen-producing plant life in the refugium leads to a wonderful natural phenomenon: the net uptake of dissolved nitrogen- and phosphorous-based compounds which are typically produced by the heterotrophic, carbon dioxide-producing fishes and non-photosynthetic invertebrates in the main tank.
Designing your refugium with a reverse daylight cycle (lights are on in the refugium when off in the main tank and vice versa) is desirable because it will act to minimize the pH swings that typically occur in reef tank systems during a normal daily cycle.
