Final Vocab Flashcards
Redox potential
The oxidation and reduction process, when electrons are lost from one Atom or molecule and gained by another.
Reef aquarium
An aquarium that incorporates invertebrates and is similar to a reef in appearance, compared with a fish only set up.
Refugium
An area that has remain unaffected by changes in climate over a period of time that have affected neighboring areas, and thus has a more ancient flora and Fauna.
Reverse- flow filtration
A biological filtration system in which water flows up into the tank through the base covering instead of having the more usual downward flow.
Reverse osmosis
A technique whereby water is forced through a membrane in the reverse way to osmosis, so that the mineral salts are left behind, resulting in pure water.
Rotifers
Planktonic organisms, used as first food for the Fry of many marine fish.
Salinity
The measure of saltiness of aquarium water. The hobbyist can measure salinity and specific gravity as one and the same.
Seagrass
An important retreat for the young of many marine fish, close in sure. Also known as eel grass
Sexual reproduction
Reproduction in which the eggs of the female are fertilized by the sperm of the male.
Silicone sealant
A slightly flexible adhesive used to bond glass or stop leaks in aquaria, or to create rock and coral formations in the aquarium itself.

Spawning
The part of the reproductive process involving fertilization of eggs.
Species only set up
An aquarium that is restricted to displaying just one species
Specific gravity
(SG) The ratio of the density of a measured liquid to the density of pure water. Natural seawater has an SG of around 1.025, but Marine aquarium fish are normally kept at 1.020-1.023
Spirulina
A type of marine algae highly valued as fish food, available in various formulated diets created especially for herbivorous fish
Stripping
The process by which the crust of a Gorgonian (the part housing the polyps) falls away.
Substrate
Aquarium base covering
Sump
And under tank reservoir that usually holds a trickle filter, mechanical and chemical filters, as well as probes and reactors.
Sushi noir
A type of food use for some aquarium fish, which is more commonly sold through human food outlets.
Sweeper tentacles
Long tentacles used by aggressive hard corals to sting other nearby corals in order to establish a territory
Swim bladder
The hydrostatic Organ enabling fish to maintain their chosen depth and position in water
Total system
And aquarium with built in sophisticated filtration and other management systems, providing full water treatment.
Trace elements
Elements found in seawater in very small quantities, often much less than one ppm
Trickle filter
A biological filter, filled with inert media.
