Carbon dioxide (CO2)
Also called Carbonic acid gas, Carbonic anhydride, dry ice (when solid).
This is a gas given off by all plants at night. CO2 is absorbed by plants during photosynthesis.
Look for activated carbon which is phosphate free. a great many carbon grades are washed with phosphoric acid in an effort to support the adsorption sites since this is cheaper than degassing.
How to use this table: Take a measurement of the KH (Carbonate Hardness) of your tank water and pH measurement. Take the KH reading and go to the relevant red column. Check the row which has both your KH reading and your pH reading.
Do carbons get full? Yes, eventually the filter carbon has bonded all the chemicals that it can handle. How long that takes depends on the quality and quantity of carbon, the load of fish waste, and several lesser factors.

The Pro-Carbon Point of View
The people that lie in this camp swear by the usefulness of carbon. They often do perform regular water changes, but feel that carbon offers a certain polishing effect that further clarifies the water.
Carbon dioxide derives from the respiration of fish, plants, and bacteria. Stirring the water enhances its oxygenation, thereby reducing the levels of carbon dioxide in the water, and passing it into the atmosphere.
Carbon that has not been treated for very long and in no particular manner germane to its ultimate purpose is, obviously, ...
Carbon Dioxide supplementation need not be complicated or expensive, and give plants an amazing boost in a tank with even moderate amounts of light, (approximately 2 watts per gallon).
Activated carbon offers important benefits for saltwater aquariums. It removes a wide variety of organics and chemicals from the water. In fact, activated carbon performs much like a protein skimmer, with the added benefit of water clarification.
Oxygen and carbon dioxide
While the air contains 20% oxygen, the most oxygenate waters rarely contain 1% oxygen. The fish have some organs, branches, allowing them to extract the most oxygen dissolved in water.
Using Calcium Carbonate without Carbon Dioxide
Recently, several products have come onto the market that consist of calcium carbonate intended to be used without a reactor.
Carbon Dioxide
Produced as a result of respiration by the fish and other aerobic organisms (including plants) in the system. The amount of carbon dioxide produced is directly proportionate to the oxygen consumed.
Carbon is absolutely necessary in aquarium filtration
I think the pervasiveness of carbon-based filtration systems has generated this myth.
Carbon Dioxide
Carbon dioxide is another gas present in water as a byproduct of the respiration of organisms in the aquarium. During photosynthesis, plants require carbon dioxide.
Carbonate Hardness (KH)
KH measures dissolved bicarbonate and carbonate ions. They are commonly referred to as the buffering capacity. KH determines how stable your pH will be and is therefore very important.
Carbon Confusion
While browsing the shelves of most fish stores, you find a multitude of products to condition water. One of the most useful products is activated carbon. There are many brands of activated carbon that vary in appearance and price.
Carbon Dioxide - (CO2) Used by plants as a nutrient. Can also be used to lower the pH
of water.
Carbonate Hardness - See Alkalinity above.
Chemical Filter - A filter that utilizes a chemical media such as carbon to clean the
water.
...
Carbon Dioxide: Carbon dioxide is an extremely important plant nutrient. Plants need it for their photosynthesis processes to provide themselves with food and energy, and therefore they must have carbon dioxide to survive.
Carbonate Hardness: The part of the total hardness that is formed by the ions of carbonates(Co3) and hydrogen carbonate(HCo3). It is symbolized by dCH. It is important to know the dCH of your water, as it affects both the ph.
Carbonate Hardness
Carbonate Hardness, also referred to as kH, is the result of contact between water (H2O) containing carbon dioxide (CO2) and lime or chalk (CaCO3).
Carbonate Hardness - See Alkalinity above.
Chemical Filter - A type of filter that utilizes a chemical medium, such as Carbon, to clean the aquarium water.
Chiller - A device used mainly in marine aquariums to help cool the water.
Carbon Dioxide: It is a molecule known as CO2, which is a biproduct of respiration. Plants require CO2 to photosynthesize, which generates molecular oxygen.
Caudal Penduncle: The long, narrow section which leads into the caudal fin (tail).
Carbon: A substance used for filtration. See activated carbon.
Carnivore: Animals who hunt and eat other animals; a meat eater. Sharks are a good example.
Caudal Fin: The single fin mounted vertically at the rear of the fish. The tail fin.
Carbon dioxide (CO2)-Measured by monitoring pH values (see above). Tested with various kit's or devices. A test of special interest to freshwater plant aquarists, and saltwater reef keepers.
carbon dioxide(Co2) - Important plant nutrient. The higher the dCH the lower the (Co2). For most aquarium plants a level of 4-6 dCH is ideal.
carnivore - Animals who hunt and eat other animals; meat eater. Sharks are a good example.
Carbon
A substance used mainly for filtration. See activated carbon.
Catfish
Species of several families with elongated sensory barbells, a scaleless skin (sometimes with bony plates), usually a bottom-dwelling creature.
carbon dioxide
Carbon dioxide (CO2) is vital to plants. Injection of co2 (using CO2 reactors or DIY systems) also softens water.
Carbonate Hardness and General Hardness
The two different types of hardness KH and GH are often confused.
Carbon Dioxide(CO2) is a gas which is highly soluble in water in relation to the other two important gases found in H2O, specifically oxygen and nitrogen.
Carbonate Hardness 16-19
In the mid 1970s a further subspecies was discovered by M. Fainzilber.
it was named L. Leleupi longoir in 1980 by Staeck.

Carbon Dosing - A method of dosing your aquarium daily with a carbon source such as Vodka, Sugar, Vinegar and Vitamin C to reduce Nitrate (NO3) and Phosphate (PO4) levels in the water. Click here to read our carbon dosing guide.
Any carbon used in an aquarium filter should be given adequate tome to expel the air in its internal matrix before it is placed on the filter.
KH or carbonate hardness performs 2 functions :
a) Enables hard corals, coraline algae to form their skeletons in conjunction with Calcium ions in the water.
If you just have high Ca, but low KH, it's not going to happen.
Activated carbon should be mentioned here too. Some brands have been reported to leach phosphates into the tank.
Activated Carbon Material used in mechanical/chemical filtration systems to remove, by adsorption, dissolved matter.

Discontinue carbon filtration during treatment
External infections should be treated with antibiotics or chemicals in the water. Copper sulfate, Acriflavine, Furan, and Terramycin may all be used externally to treat Columnaris.
Activated carbon- many filter manufacturers state that you need this in your filter. They would say that, since you have to replace it every 4 weeks! ...
Ammonia and carbon dioxide suffocating fish in container.
White water lines. Plants die, fish have frayed fins.
Hard water supply. Seashells or limestone in tank.
Chemipure is a carbon substitute. I have found it to be a very good filter additive that will keep the water fit for fish for up to 6 months before needing replacement. I personally use Chemipure as my only chemical filtration agent.
Granular activated carbon (GAC) is manufactured from carbon, typically coal, heated in the presence of steam at very high heat.
activated carbon This is carbon, looking like crumbled charcoal. It can absorb many compounds out of the water, and is especially good at removing yellowing compounds to keep the water clear.
Carbon is also beneficial but Purigen is superior. It is rechargeable and will also remove log stains from your tank (That is if you did not use the Charred wood from A+RR Inc). Remember to rinse loose particles out before adding to your filter.
Activated Carbon - Used in the aquarium filter to remove impurities from the water and keep it clear. It is also used to absorb and remove medicines used in the aquarium after the treatment is finished.
Alternatively, the ammonia can removed by filtering the water through zeolite or carbon before adding it to your tank. [Note: folks report mixed success with this.
Carbonate hardness, specifically, should remain between 6 and 8 dKH. Plenty of hiding places should be provided; often plants are preferred. The addition of peat moss to the tank as a substrate or in a filter is sometimes used to condition the water.
It draws water from the tank and passes it through filter material such as sponges, carbon and zeolite. The sponge can provide mechanical filtration by removing particles.
This is achieved through mechanical filtration, chemical filtration (via carbon), and biological filtration (via bacteria growing on the filter media).
I simply have the addition of a normal external power filter which allows me to insert into the filter whatever filtration components (zeolite, carbon, etc.) I want to. If you have the cash, then your best bet is probably a cannister filter.
The reason for this is that many invertebrates, like corals, build a skeleton or shell of calcium carbonate.
- Reduction of toxic carbon-dioxide level (Co2 level) which happens to be a critical factor causing constant fish deaths. The plants use up the Co2 in the process of food formation.
These compounds form a skin which inhibits the exchange of gases such as carbon dioxide and oxygen from transferring between the water and the atmosphere. An Overflow system is a box or pipe placed in the corner or middle of the back of the aquarium.

Air pumps are employed to adequately oxygenate (or in the case of a heavily planted aquarium, provide carbon dioxide to) the water.
They readily assimilate carbon from bicarbonates (as opposed to carbon dioxide) and thus do exceptionally well in harder water; some can even tolerate brackish water that is not too high in salt.
This allows carbon dioxide to be exchanged for oxygen. Oxygen is important for the fish so they don't suffocate and also for the beneficial bacteria we want to grow in the filter.
At the top of the tubes are filter media inserts, usually carbon or resin, to provide some chemical filtration, though these must be changed frequently.
The emphasis for filtration was to remove solid fish waste and detritus, and to use carbon to remove discoloration and odors. This approach relied on mechanical and chemical filtration to supplement the balanced aquarium technique.
magna tends to prefer harder water (170 mg carbonate hardness) and D. pulex a little less hard (90 mg carbonate hardness).
This filter uses activated carbon and glass wool (or peat moss) to serve as biological filters. They absorb and retain the fine waste products that float in the water, along with the harmful nitrates and ammonia by-products.
