Catalytic Activated Carbon, 2.25 lbs, Enhanced carbon rapidly removes Chlorine, Chloramine, Organics and Odors - For aquariums, RO/DI Filtration Systems

Catalytic Activated Carbon is a highly effective and rapid method to remove harmful dissolved organic compounds (DOCs) and toxins like chlorine, chloramines, and hydrogen sulfide from aquarium water. This carbon also clears out yellow tints in your water, eliminates odors, removes toxins and reduces algae growth. Regular use greatly improves water clarity and light penetration in your tank, allowing your corals to receive more light and improve growth and appearance. 

This virgin activated carbon comes in a granular form, made from selected grades of coconut shells. Originally produced for water purification, this type of carbon can also be used in RO/DI filtration systems. 

STARTING INSTRUCTIONS

Measure out the amount to be used in your tank. The recommended amount is up to 1.25 cups per every 100 gallons in tank volume, or 2 tablespoons per every 10 gallons of tank volume. The recommended method for use is in a mesh filter bag. 

MESH FILTER BAG

Add carbon to your fine mesh filter bag. Rinse the carbon under water from your tank or RO/DI water about 30 seconds, or until the water runs clear. Avoid grinding the carbon in the bag while doing so, since this may create a fine particle dust that will need to be rinsed out. Place the bag into your sump or a high flow area of your tank to ensure water is being filtered well through the carbon.

MAINTENANCE INSTRUCTIONS

Remove carbon after 3-4 weeks based on tank needs and water clarity. Use as needed.

To determine when to add new carbon, a quick method to use is a bucket test. When doing a water change, add tank water to a white bucket, and compare to fresh RO/DI water in another white bucket. If a yellowish tone is observed in the tank water, add carbon as indicated above. 

If an accurate measurement for when to use this carbon is desired, an ICP test with values indicating dissolved organic carbon (DOC) levels can be used. For example: SAC254 on an ICP-MS test is an indirect measure of the DOC levels. Do not use if DOC levels are below the optimal ranges, as this may adversely affect coral growth.
