Overview
*
Coconut-based activated carbon for marine and reef aquariums
*
Rapidly removes dissolved organics for high aquarium water quality
*
Ultra low ash & leachable phosphate levels suits reef aquarium use

The ultimate activated carbon for marine and reef aquariums. Red Sea REEF-SPEC Carbon boasts unique technical characteristics to address specific requirements of reef aquariums. Granule size and micro/macro porous structure ensure a very high total adsorption capacity and rapid extraction of the small organic pollutants missed by conventional filtration and protein skimming. Highly activated coconut-based carbon features extremely low phosphate leaching and minimal ash content while also not affecting the pH of aquarium water.

Usage Guide
Organic Load and Yellow Tint Removal: The recommended dosage of Red Sea's REEF-SPEC Carbon is approximately 50 g (100 ml) per 200 L (50 gallons) for a period of 1-2 months for a moderately stocked reef aquarium.

Post-Medication Treatment: The recommended dosage of Red Sea's REEF-SPEC Carbon to adsorb medication residuals is approximately 100 g (200 ml) per 200 L (50 gallons) for a period of a week.

Ozone Post-Treatment: The recommended dosage of Red Sea's REEF-SPEC Carbon to remove residual ozone is 50 g per 50mg/hr of ozone injection. The carbon should be placed at the ozone reactor/ protein skimmer outlet. Carbon should be replaced once it has reached approximately 50% of its original volume.

Tips on using Reef Spec Carbon in a reef aquarium
The adsorption activity of the carbon media relies on a good carbon/water contact and therefore moderately active water flow will increase the efficiency. Strong water flow will reduce the contact time and interfere with the adhesion process of the organic molecules to the carbon. Strong water flow may also cause the granules to grind against each other, releasing carbon material to water.

For Best Results:

  • Remove any fines, by rinsing carbon under tap water.
  • Due to air trapped in the pores carbon will float and therefore it is recommended to soak the carbon in RO water until all of the air has been released.
  • Place the carbon in a location with an active flow of 1000-1500 lph (250-400 gph) per 50 g carbon.
  • Replace carbon every 1.5 - 2 months. Note: When carbon becomes saturated with organics, it may start adsorbing some of the trace elements from the seawater.

General Information
The role of Activated Carbon in the reef aquarium

Why do we need to use carbon in a reef aquarium?
There are organic pollutants that can only be removed from reef aquarium water by active carbon. The reef aquarium is a closed artificial ecosystem where living creatures continually produce organic waste consisting of proteins, fats, carbohydrates, organic acids and phenols.

If allowed to decompose, the organics will fuel the activity of many unwanted microorganisms in the aquarium, increasing the total oxygen demand (BOD, COD) which will cause a reduction in Redox potential, as well as causing excessive production of CO2 by bacterial respiration, which will reduce pH. Furthermore, there will be an increase in nitrogenous and phosphorus compounds, encouraging growth of nuisance bacteria and eventually of nuisance algae. The accumulating organics also has a significant effect on light penetration, especially in the blue and near UV spectrum that stimulates coral growth.

Stripping out the organics from the water is therefore crucial for the success of the aquarium. Using strong protein skimming, fine mechanical filtration and healthy biological filtration (nitrification and de-nitrification) will treat the large organic particles and the end products of the organic decomposition processes. However, there are many small organic particles that can only be treated by very fine mechanical micro-filtration using activated carbon.

How does activated carbon filter water?
Scientifically speaking, carbon removes the organics from water by a physical process called adsorption. Within a reef aquarium, the submicroscopic pores of activated carbon is the final stage of the mechanical filtration process, adsorbing the organic molecules that are too small to be removed by even the finest mechanical filters or physically removed from the water by protein skimming.

Adsorption can be thought of as the adhesion of a molecule to surface by attractive forces. This occurs within the submicroscopic pores of the carbon because the attractive forces between the organic molecules and the internal surfaces of the carbon are far greater than the attractive forces that keep them dissolved in solution. This will continue until all of the surface area inside the carbon is used up and it becomes saturated with organics.

What is activated carbon?
Activated carbon is an extremely porous material with a sponge like structure but with a very large internal surface area relative to its physical size. It is produced from many organic materials that have a high carbon content such as coconuts shells, nutshells, lignite, bituminous coal or anthracite. The carbon-based material is "activated" through physical modification and thermal decomposition in a furnace, under a controlled atmosphere and temperature. The activation process significantly increases the surface area per unit volume of a fine network of submicroscopic pores, which is what gives activated carbon its ability to act as a filter material. The specific source of the carbon and the specific activation process determines the physical characteristics of the finished product. There are many different grades of activated carbon and therefore they must be selected specifically for each and every application.

About Red Sea
Since its inception over 25 years ago, Red Sea's vision has been to create a world in which marine and reef aquariums are the aquariums of choice for all hobbyists. This passion has guided the company throughout its product development and design.

Red Sea is committed to providing complete reef solutions, allowing hobbyists like you, to focus on the beauty of your reef inhabitants rather than worry about water chemistry or the suitability and compatibility of aquarium equipment.

Several significant advances in reef keeping have been made possible due to Red Sea's commitment to research. This ongoing, original research carried out by Red Sea's dedicated team of biologists, chemists and engineers, brings great benefits to hobbyists worldwide.

Red Sea's unique research into the biochemistry of corals and their relationship with the surrounding seawater resulted in the development of the Reef and Marine Care Programs. Highly advanced yet easy to implement, the programs empower hobbyists with the knowledge and materials to understand and control the fascinating environment within their aquarium.

In keeping with the company's objective to make successful reef keeping accessible to a wider audience, from novices to experienced hobbyists, Red Sea developed its ground breaking range of MAX aquarium systems. Fully equipped to support even the most delicate stony (SPS) corals, the MAX systems are designed to blend into any contemporary home environment.

Red Sea's wide range of unique solutions enable you to spend more time enjoying your piece of coral reef, achieving long-term success and stunning results.

Mechanical filtration can greatly improve the health of most aquariums, and is also important for the efficiency of your biological filtration. The process is simple: mechanical media strains solid debris.
Biological filtration is the action of bacteria breaking down dangerous ammonia, converting it to nitrite, and then converting nitrite to less toxic nitrate. This article discusses how the process works.
While most aquarists agree biological filtration is imperative for your aquarium's health, not all agree that mechanical and chemical filtration is absolutely necessary.
