Full Answer

What does activated carbon do to fish?

You see, activated carbon actually absorbs many different medications, preventing them from benefiting your fish. If you plan to medicate your fish, remove all traces of activated carbon from your tank. Once the treatment is over, return the activated carbon to remove any leftover medication from the water.

What type of activated carbon is best for aquariums?

Bituminous coal-based activated carbon like Marineland Premium Activated Carbon and API Activated Filter Carbon are recommended for freshwater and marine aquariums. You’ll often see generic pelletized coconut shell activated carbon sold as special “reef approved” or similar marketing.

Why is carbon bad for fish?

Admittedly, it’s not just organic chemicals that carbon removes, and as such it has been implicated as a cause of problems to some fish, even as the cause of a disease. It’s true that carbon is unselective in what it removes.

What does activated carbon not do?

What Activated Carbon Doesn’t Do. There are several important toxins that activated carbon does not remove. Most notably, it does not move ammonia, nitrite or nitrate. Therefore it does not aide in toxin removal during the initial aquarium setup.

Can I put activated carbon in my fish tank?

While it is technically possible for activated carbon to release the pollutants, this would require some changes to the water chemistry that simple will not occur in your aquarium. So, don't worry if you forget to remove the carbon from your filter – it won't harm your aquarium. Activated carbon is perfectly safe.

Does activated carbon increase pH aquarium?

Some people feel strongly against the use of activated carbon due to the amounts of phosphate it can bring to the water which will inevitably lead to cloudy water and algae growth. Activated carbon will also raise the pH in the aquarium to a certain degree depending on the ash content and quality of the active carbon.

How long is activated carbon good for in aquarium?

Activated carbon will be effective for about 3-6 weeks in the average freshwater or saltwater aquarium setting. Aquarium carbon should be placed in an area of high flow so that as much water as possible is passed through to remove unwanted odors, colors, and impurities.

Can you use too much activated carbon?

Note: It is possible to overdose from taking too much activated charcoal, but it's unlikely to be fatal. However, you should seek immediate medical attention if you believe you've overdosed on activated charcoal. Overdosing could present as an allergic reaction, vomiting, or severe stomach pain.

Will activated carbon clear cloudy water?

Adding activated carbon media or activated carbon pads to the filter will help clear the water and adsorb nutrients that feed the bacteria bloom.

Will activated carbon lower nitrates in aquarium?

Carbon, at least the carbon that can be safely used on a reef tank will not remove ammonia, nitrite or nitrate. As was said, skimming and water changes help but having a good DSB is the best solution.

Does activated carbon remove algae?

Algae bloom (green water) Activated carbon can't remove algae itself, but instead works by neutralizing the organic matter and chemicals that help cause blooms.

How often should I change carbon in fish tank?

If you use filter pads or bagged carbon, you need to change only the carbon; the pad or mesh bag is reusable and only needs changing when it shows signs of wear. A yellowish tint to the water or an unpleasant odor are physical signs that your carbon needs changing.

How does activated carbon work in a fish tank?

Activated carbon is able to remove contaminants from your fish tank via two different methods, either through absorbing the contaminants, or through catalytic reduction, in which the negative ions contained in the contaminant are drawn to the positive ions that make up the carbon.

Why add activated carbon to water filter?

The Use and Efficiency. The activated carbon is added to the filtration system to perform chemical filtration, some keepers use it all of the time, while other keepers only add this to their filters when removing medications from the water after a full treatment course, this is purely a matter of choice. It is up to you if you feel that you need ...

How does an activated carbon filter work?

An activated carbon filter works by the law of attraction. When water passes over the positively charged carbon, the impurities in the water which have a negative charge will be locked into the activated carbon filter. Usually activated carbon filters use either granular activated carbon or powdered block carbon.

What is activated carbon?

For many years, carbon has been used as an agent to remove impurities from air and water. Activated carbon is one of the most effective absorbents currently used. Activated carbon is carbon which has a positive charge added to it, which makes it much more effective at absorbing impurities and chemicals. An activated carbon filter works by the law ...

Why do you need to run carbon in an aquarium?

It is up to you if you feel that you need to run carbon in the aquarium, often it can help to polish the water to a clear grade. The efficiency of activated carbon filters are dependant on two factors. First, the amount of activated carbon which is contained in the filter and second, the amount of time the impurities stay in contact with the carbon.

What are the inorganic particles that cannot be absorbed by activated carbon filters?

There are some inorganic particles that cannot be absorbed by activated carbon filters, such as arsenic, asbestos, cadmium, chromium, copper, fluoride, thallium, and mercury. To remove these kinds of contaminants you have to have either a reverse osmosis filter system or a water distiller.

Which is better: powdered block or activated carbon?

Both types of filters are effective, however the powdered block carbon filters do tend to remove more impurities than its counterpart. Activated carbon is the best carbon media to use, there are cheaper versions of carbon that are not activated, but this compound is not up to the job and not as efficient as the more expensive activated one.

Why use activated carbon in water?

activated carbon removes color pigments in the water, along with toxins. The only reason you would want to use it is to clear cloudy water, or remove toxins. Thanks to Gizmo for trying to answer my question.

Can fish die from carbon?

First of all, to answer your question: No, your fish will not die from ingesting carbon. You might want to vaccuum or pick it out anyway, but it won't kill them. It happened to my sister once; she accidentally spilled some into her tank, her oscars went for it, and she was freaked out about it. But they were fine.

Can carbon in a filter kill it?

jrman83 said: Loose carbon in a filter can destroy it. Definitely need a filter bag. The stuff that shot into your tank isn't doing you any good. Carbon generally is not very effective in filtering water for cloudy conditions, although I am sure it works for some. Click to expand...

What is activated carbon made of?

Activated carbon is manufactured from carbon, typically coal. The two most common forms are bituminous and lignite based. Another form that is not made from coal is coconut shell based. Activated carbon is processed into three forms: Granular, pellets and powder. The granular and pellets are most commonly used in aquarium filters.

Activated carbon can also remove the trace elements and minerals that are important to your fish, invertebrates, and corals. A recent study has found that the heavy use of activated carbon in marine aquariums can cause Head & Lateral Line Erosion disease (most often seen on fish in the Surgeonfish Family).

Should you use carbon in an aquarist?

There has been an ongoing controversy amongst aquarist for years if you should use carbon continuously, just when needed, or even at all. The trend leans towards using carbon only when there is really a reason its use is warranted, because a healthy system, particularly one that has an adequate protein skimmer installed should not require it. Richard Harker's iodide absorption test results lead him to conclude that, "the use of carbon has minimal impact on iodide concentrations and that passive use of carbon has no lesser effect on iodide levels than active use."

Can carbon absorb more than it can hold?

Like most other absorbing compounds, carbon can only absorb as much as it can hold. Once it has taken in as much as it can, it becomes exhausted, which means it is unable to absorb anything more.

Can you put carbon in a power filter?

What is the role of carbon in removing dissolved organics?

Dissolved organics are a food source for heterotrophic bacteria, which can in turn out compete nitrifying bacteria for space and oxygen. The sole limiting factor affecting heterotrophic bacterial growth is the availability of organics.

How long does carbon last in water?

This is true. Under most conditions, carbon has a functional life of one to two weeks, perhaps even shorter. The average functional life of carbon is difficult to determine as many variables apply, such as the amount of dissolve organics in the water, the effectiveness of mechanical filtration, and the amount of carbon in use.

What is industrial use of carbon?

Industrial use of carbon involves the capturing of a specific substance at one pH extreme (below 4 or above 10) and then reclaiming the substance by converting to the other pH extreme. If a pH shift of this magnitude occurs in an aquarium, carbon leaching organics back into the water is the least of our worries. 5.

How does activated carbon remove contaminants?

Activated carbon removes contaminants through two methods, adsorption and catalytic reduction (negative ions in the contaminant are drawn to the positive ions in the carbon). In general, organic particles are removed via absorption while chemical contaminants are removed via catalytic reduction.#N#Of the organic substances removed by carbon, the two primary categories are tannins and phenols. Tannins discolor the water and phenols give the tank a fishy smell.#N#Carbon will also remove toxins such as pesticides, tar and nicotine (from cigarette or cigar smoke), detergents, hydrogen sulphide, copper, arsenic, bleach, and host of other contaminants.#N#Additional details on exactly what carbon removes are identified in the below table:

How to choose the best carbon?

In addition, there are several guides to selecting the best carbon: If the label provides details such as ash content, porosity, and phosphate content, then chances are it is from a reputable manufacturer and is a quality carbon. Compare weight and volume. The greater the porosity, the better the carbon.

Controversy

Types

Sources

  • There are also different sources for the carbon itself, each resulting in different possible pore size. Materials such as coal, coconuts, peat, and wood are all used to create activated carbon. For aquariums, the best source is bituminous coal.
See more on thesprucepets.com

Chemistry

  • Activated carbon adsorbs a number of dissolved contaminants such as chloramines and chlorine, tannins (which color the water), and phenols (which cause odors).

Prevention

  • Heavy metals, such as iron, are also not removed. If your water source has heavy metals, use a water treatment product before putting the water into the aquarium.
See more on thesprucepets.com

Treatment

  • If you are having difficulties with persistently elevated phosphates and can find no other cause, remove the activated carbon entirely. Perform normal tank maintenance for a couple of months and see if the phosphates remain elevated or are reduced. If they stay high, the carbon was probably not the reason for your elevated phosphate. Activated carbon will adsorb many medica…

Safety

  • Activated carbon will lose its effectiveness rather quickly if exposed to lots of debris from the aquarium. Therefore, carbon should be placed after the mechanical filtration media in the filter. Keep in mind that if you do not keep your tank clean, and debris builds up in the filter, the activated carbon will not be effective.
See more on thesprucepets.com

Effects

  • Since activated carbon binds with the compounds it removes, it eventually becomes saturated and can no longer remove additional contaminants. Therefore, it must be regularly replacedonce per month is usually sufficient. Longer intervals between replacement will not harm the tank, but the carbon will gradually lose its ability to remove toxins from the water.
See more on thesprucepets.com

Examples

  • Stories about recharging activated carbon abound. Some even give step-by-step instructions, which generally involve baking the carbon in your oven. These stories are myths. The temperature and pressure required to recharge exhausted activated carbon cannot be achieved in your kitchen oven.
