How does activated Carbon filter water?

Carbon removes the organics from water by a physical process called adsorption. Within an aquarium, the submicroscopic pores of activated Carbon is the final stage of the filtration process, adsorbing the organic molecules that are too small to be removed by by protein skimming.

Organic Load & Yellow Tint Removal

The recommended dosage of Red Sea’s REEF-SPEC Carbon is approximately 50 gr (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 gr (200 ml) per 200 L (50 gallons) for a period of a week.

Ozone Post-Treatment

The dosage of Red Sea’s REEF-SPEC Carbon to remove residual ozone is 50 gr per 50mg/hr of ozone injection. The carbon should be placed at the ozone reactor/ protein skimmer. Carbon should be replaced once it has reached 50% of its original volume.

Usage tips

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.

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 gr 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.
