" Create a shelter in your aquarium "
A refugium helps control nitrates and phosphates in a natural way by providing space for macroalgae to grow. Macroalgae will compete with nuisance algae within the aquarium, and assist your filtration system in cleaning up the water column.
The HOB-R will also harbor many beneficial invertebrates which consume uneaten food or detritus. Invertebrates such as copepods and amphipods can be found living in the sand and liverock in many aquariums, however, these invertebrates can often diminish in numbers as they are preyed upon by inhabitants. Adding a refugium will shelter these tasty fish snacks, ensuring that there is a colony consistently providing to the food chain and helping in the break down of organics, in safety.
