Text: 90 percent of all living matter (except bacteria) in the ocean is algae of all forms and colors. The remaining 10% (except bacteria) of all living matter in the ocean is: Corals, Plants, Sponges, Worms, Snails, Clams, Octopi, Shrimp, Crabs, Pods, Urchins, Starfish, Small Fish, Medium Fish, Big Fish, Sharks, Whales, Giant Squids, and Everything Else. The algae is what does all the filtering of the waste from the animals, and the algae is also what feeds all the animals through the various food webs.

Aquariums, however (especially ones without refugiums), have no algae to do the filtering or feeding. So all the filtering has to be done manually with equipment, and all the feeding has to be done manually too. At least with a refugium, there is some filtering and feeding, although most refugiums are far too small to do all of it. Scrubbers are powerful enough to do all the filtering by themselves, and can do a lot of the feeding too, if copepods are the food that is desired.
