The refugium is an auxiliary tank on your main, display tank. It serves as a sort of refuge for both primary producers and primary consumers (i.e. intermediaries) such as pods. There, desirable and beneficial macroalgae are cultivated out of the reach of large, gluttonous herbivores such as tangs. Pods proliferate there too, safe from the constant predatory pressure of small fishes like damsels, gobies, etc. Even so, as the pods reproduce, they drift out of the refugium into the main tank to continuously feed fishes, corals, and so on. As the macroalgal bed grows to maximal carrying capacity, it is harvested and either discarded or (better yet!) fed out as a nutritious live veggie for fish and invert herbivores in the main tank. - Thanks AlgaeBarn
What's not to love about refugiums and why would you not set one up on your reef tank? Let's talk about it!
1. Why don't you have a refugium running on your reef tank?
2. If you are running a refugium tell us about how they are worth setting up and maintaining?
