as for fuge what exactly is a fuge.as far as i have read its just sand/and rock.what else is in a fuge.i dont need macro because of the scrubber and i have 40+ lbs of rock rubble on the left section of the sump.i do have about 50 lbs of sand argonite in a bucket though.
A refugium is a place where tiny critters like copepods, amphipods, isopods and such can populate undisturbed. If you have a critter in the tank that eats them (all fish do) they are not in a safe place to just populate. The sand and rock even macro algae are breeding places. They have the same thing in the main tanks but the fish deplete the population. By having a refugium they repopulate the tank as they are eaten so that a fish like the mandarin has a steady supply of food.
The sand in the refugium helps take away nitrates. The same happens in the main tank unless you have a sandsifter…again the sandsifter may deplete the sand and disturb it in the main tank, but the refugium remains untouched to do its job.
So if you stock the refugium the same way you stock your tank, you simply have two tanks up and running. There is no refuge for the tiny critters. So it isn't just some sand and rock and sometimes macroalgae. You do not have to have macroalgae in the refugium.
You have allot of rock and that’s really good filtration and I bet there are plenty of little critters in there too. So you really don’t NEED a refugium..it was just a suggestion.
