This is a Live Rock, Refugium, and Skimmer only system. No other filtration.
Using a Refugium is a great way to lower phosphates
and nitrates in a system.
It is a 46G bowfront with a 40g sump/planted Refugium housing your Helix 5000!
For filtration the trigger system ruby 36 sump Refugium was installed measures 36x15x16 holds
roughly about 35 gl of water.
Nigel also chose the Orphek PR72 Reef Pendant for his Refugium which is shown on the left side of his system.
Within the south-central region, an area known as the Adelaide Geosyncline
has been recognised as an important historic Refugium for several animal and plant species.
More importantly MCEs may act as refugia for shallow-water coral reefs
and their associated biota and therefore increase their resilience to natural and anthropogenic disturbance.
Over periods of ecological changes, biogeography includes the study of plant and animal species in:
their past and/or present living Refugium habitat; their interim living sites; and/or their survival locales.
For MCEs to act as refugia they must share species with shallow-water reefs,
be at least partially protected from disturbances that impact shallow-water reefs and there must be connectivity amongst populations of corals and associates across the depth gradient.
