A mispelling of Chaeto, short for Chaetomorpha algae, often used in refugiums.
A piece of equipment used to cool down the water in an aquarium. Chillers are available in different types and sizes, including one that hooks up in-line with the water flow of the tank and one that drops into the sump. They all feature a thermostat for maintaining a constant temperature. Larger tanks require larger chiller units. These are generally used when the water temperature cannot be kept below 82°F by itself.
A metal used in the form of copper sulphate to cure diseases and parasite infestations on fish. Copper is highly toxic to marine invertebrates and should never be used in a nano reef.
Algae that form solid calcium carbonate accretions. Coralline is desirable in reef aquariums, and helps prevent undesirable algae from growing. Covers rocks, aquarium walls, and equipment. Usually pink or purple, turns white when it dies.
A subphylum of Arthropoda that includes shrimp, mantis shrimp, lobsters, crabs, water fleas, copepods, crayfish and wood lice. There are almost 40,000 described species of crustaceans. The Crustacea are mainly aquatic, but include some semi-terrestrial and terrestrial groups

NO3 the final product in the nitrogen cycle. It is not toxic, but can be dangerous at high levels. Nitrate is created by the oxidation of nitrite by nitrobacter bacteria. In a nano reef, nitrate levels should be kept below 10 ppm.
The process by which ammonia is changed to nitrite, then nitrate, and finally nitrogen gas. See nitrogen cycle.
NO2 the second product in the nitrogen cycle. Nitrite is a highly toxic substance that is produced by the oxidation of of ammonia by nitrosomonas bacteria. It is easily removed with biological filtration.
The nitrogen cycle describes how organic wastes break down in the aquarium. Fish wastes naturally decompose into ammonia, which is highly toxic. Nitrosomonas bacteria process the ammonia into nitrite, which is also toxic. Nitrobacter bacteria then break down the nitrite into nitrate, which is much less harmful. This is as far as the cycle goes in most tanks, though under the right conditions, the nitrate is further broken down to free nitrogen gas.

This mechanical filter, also called a foam fractionator, sends many small bubbles through a column of water to separate dissolved organic compounds from the water. They come in many varieties such as venturi, counter-current, and co-current. They are only effective in salt water. They may be placed in the tank, hung on the side, or placed in a sump.
Poly vinyl chloride, a type of pipe used for plumbing aquariums
A tank (other then your display) set-up specifically to monitor and prevent outbreaks of problems in your main display aquarium when you bring home new fish, inverts, etc. Usual time in a QT is 2-4 weeks. Most commercial Aquariums (Monterey Bay, Aquarium of the Pacific, etc.) always Quarantine for minimum of 4 weeks.
Something having a polished surface for reflecting light. Reflectors are placed around aquarium lights to guide and direct their light downward.
An area separate from the display tank (often in a sump), that is meant to be a refuge for organisms like "pods". Macroalgae is often found in refugiums as both a habitate for the pods and a form of nutrient export (through trimming excess growth). Refugium organisms are either not widespread in the main tank (i.e. the lack of pod predators) or are not desired as display species; although some refugiums achieve a display quality as highlight organisms like sea grasses.
This is a purification method for tap-water. Prefiltered tap water is pushed through a reverse osmosis membrane. Water that makes it through is considered pure, while water that does not, is sent through a special tube and is rendered impure. As it relies on water which is able to pass through the membrane, it also generates a large quantity of "waste" water which cannot be used. This is one of the best, but slowest methods of tap water purification. Reverse Osmosis units produce purified water at extremely slow rates, sometimes as low as 10 or 15 gallons per day (depending on your water pressure and temperature).
See Reverse Osmosis
Reverse osmosis with deionization. DI filtration alone is highly effective at purification, but the filter media exausts quickly. By adding it to the end of a reverse osmosis filter, near 100 percent purity can be acheived, while extending the life of the DI resin.

The ratio of density of a given liquid to that of pure water. Specific gravity is used to measure the salinity of seawater as compared to distilled water. Distilled water has a specific gravity of 1.000 while natural seawater has a specific gravity of about 1.025. SG readings are also effected by temperature.
Small Polyped Scleractinian, Small Polyped Stony Coral

Slow Tissue Necrosis
A container that houses items such as wet/dry filters, skimmers, heaters, and refugiums. Sumps are generally kept below the display aquarium. Water drains into the sump from the aquarium above, and is pumped back to the aquarium.
A polyp that acts in an aggressive manner by stinging neighboring corals and sessile invertebrates.
A coral polyp tentacle that has an increased number of nematocysts and elongates in order to 'sting' neighboring corals and sessile invertebrates. A tool in the competition for space and resources.

Very High Output (VHO) lights are specially designed fluorescent lights that give off a much higher intensity light than regular fluorescent bulbs. This makes them much more effective as light sources for reef systems, since many corals require strong light. As with all fluorescent lights, VHOs require a ballast unit for operation.
See Water Change
The process of removing a certain percentage of water from a reef aquarium and replacing it with newly mixed saltwater. This process helps remove disolved organics, nitrates, detritus, and replenishes trace elements. In a nano reef, 10 percent changes are recommened every week, or 20 percent every other week.
A biological filtration system that is exposed to the air to aid nitrification. This system typically consists of a large box that is placed underneath the aquarium. Water passes down into the filter over a filtration medium where bacteria remove toxins. The water is then pumped back up into the tank. A sponge or other mechanical filtration medium may also be used in a wet/dry filter.
