This is a consolidation of the sticky in the general forums... too many users to give credit to, but I'm basically copy and pasting everything from the sticky into one massive list. I see that in the original sticky, the original poster added "submitted by ____". I think we could forego this and just give a generic blurb at the top saying that this a list compiled by members of the community.

This is just for the glossary. I will do the same for FAQ and for Useful links, which I think would go great under General Setup & Maintenance > Resources.

I've gone through and made changes to the definitions as appropriate. Please chime in if you think something needs to be changed.


AC - (1) Activated carbon, chemical filtration media; (2) alternating current

AGA - All-Glass Aquarium, an aquarium manufacturer.

Algae Eater - A fish that is prized by aquascapers for its algae eating.

Amano - (1) Reference to Takashi Amano, an accomplished aquascaper whose name has come to define a style of aquascaping; (2) Short reference to a species of shrimp used by Takashi Amano for their great algae eating ability.

Aquarium - A container used to house fish, plants, invertebrate and other aquatic life. Usually made of glass or acrylic but can also be made of other material such as wood.

Aquascaping - The process of arranging rocks, driftwood and plants and pruning the plants for aesthetics.

Ballast - A device used to start a gas discharge lamp, and once the lamp is started, to limit the flow of electric current.

BBA - Black Brush Algae, not always black but grows in tufts.

BGA - Blue Green Algae aka cyano bacteria.

Biogenic - Decalcification - When CO2 is deficient the plants can suck it right out of the hardening constituents of the carbonate hardness, thus raising pH.

BOD - Biological oxygen demand.

BPM - short for bubbles per minute, the count of bubbles in a bubble counter for a CO2 system, a unit of measure for CO2

BTW - Short for "by the way"

Bubble Counter - A small cylinder half full of water with a CO2 input tube and an output tube. Bubbles form and co2 gas enters the input chamber and then to the output chamber. Bubbles form in the water to help the user gauge the co2 flow rate.

Buffers - products used to raise or lower alkalinity and acidity.

CAE - short for Chinese Algae Eater, an infamous algae eating fish.

Canister Filter - These filters differ from the "hang on the back of your tank" filters in that they are external to the tank. They have an input and output hose. Water leaves the tank, enters the canister for filtration, then re-enters the tank. These types of filters are generally more efficient than "hang on" filters and are desirable for aesthetics as the filter can be hidden.

Canopy - Sits on top of tank usually contains lighting.

CO2 - Carbon Dioxide, generally used in planted tanks with heavy lighting (greater than 2WPG) to accelerate plant growth. Injection usually done via DIY CO2, pressurized CO2 or CO2 tablets. CO2 injection is usually done with care however as it lowers your waters pH.

CO2 regulator and solenoid - A guage and controller that attaches to a pressurized CO2 bottle with a plug to activate and deactivate CO2 injection. Solenoid usually plugs into a timer or pH controller. Regulator drops the cylinder pressure to a working pressure. Some have bubble counters built in.

CRS - Crystal Red Shrimp

CTA - Cellulose triacetate, type of RO membrane generally for water filtration

Cutting - Detached parts of stem plants for replanting.

Cyano - Cyanobacteria, a nuisance algae

DC - Direct current, a type of power

Demineralization - extraction of dissolved salts in the water byway of ion exchange or RO.

DI - Deionisation, type of water purification, a common part of some water filters

Diffuser - Inserts gas into water as very tiny bubbles and spreads the gas out. Generally used in smaller tanks to inject CO2

DIY - short for Do it yourself

DIY CO2 - Do it yourself CO2, generally a system designed to produce CO2 through chemical reactions, usually for smaller tanks

Dormant Periods - Some plants observe it to adjust to native (dry)seasonal fluctuations.

Eco-Complete - A common premium substrate for planted tanks

EI - (Estimative Index) Fertilizer Dosing Method

Emersed Plant - When the plant is grown out of the water. That includes in regular soil or fluorite or whatever substrate, or it can mean that the plants are allowed to grow out of the water (ie: when the plants get too high in an aquarium) Emersed plants flower and bud. Some submersed plants can be grown emersed, but not all of them.

LFS - Live/Local Fish Store

Low-Tech Tank - Used to describe a tank with little growth aid, generally less than 2 WPG and no CO2 injection

LPH - Liters per hour

MJ - Maxijet, powerhead manufacturer

MTS - (1) Malaysian trumpet snails; (2) short for Multiple Tank Syndrome, referring to the addictive nature of this hobby and the desire to purchase more than one tank

It is a valient effort! Pretty good as well.

There are a few things.

Personally, the references to "net speak" always seemed silly to me. I like a technical glossary as it seems more like a legitamate piece of work. I thought the last thread was dopey because of all the nonesens that was added in.

It seems like there are a bunch of saltwater terms in here.....do you really need them?

CTA - Cellulose triacetate, type of RO membrane generally for water filtration

NSW - short for Natural seawater

RC - short for reefcentral.com, a popular saltwater reef site

Refugium - A tank that sits external to your main tank but shares the same water via an overflow or attached to a sump. Refugiums are generally used to isolate certain plants or grow items that need to be isolated such as macro algae.

TFC - Thin film composite, type of RO membrane, generally for water filtration
I have been on this forum for years and have rarely if ever seen some of those terms used.

The overtly obvious:

Algae Eater - A fish that is prized by aquascapers for its algae eating.

Aquarium - A container used to house fish, plants, invertebrate and other aquatic life. Usually made of glass or acrylic but can also be made of other material such as wood.

DC - Direct current, a type of power

Evap - Short for evaporation

These need to be clarified:

Flourish - A family of Seachem.com products that will add plant nutrients to the tank.

Flourite - A common premium substrate for planted tanks

Greg Watson Ferts - GregWatson.com is a common retailer of fertilizers for planted tanks. This site is popular because they sell dry fertilizers in quantity which equals significant cost savings per dosing unit.

Latterite - A common tank substrate - NOT a substrate

Lumens - A unit of measure for light output submitted by Fish Newb The lumen can be thought of casually as a measure of the total "amount" of visible light emitted.

Onyx - A common premium sand for planted tanks



I'd be happy to help with the changes.

Consider adding things that are plant specific...like major plant genus.

Cryptocoryne - Crypts
Echinodorus - Swords

Things like that are more more important to a good planted aquarium.

Impressive list! I have a couple more to expand it a bit.

AC can also be used to mean "AquaClear" filters.

GAC to mean "Granular Activated Carbon" ...I think I see that more than AC for activated carbon, so probably ought to be included too.

UVS for UltraViolet Sterilizer, I use that most of the time.

NO3, PO4 & KH2PO4 for the sake of completeness.
