Activated carbon (e.g. JBL Carbomec and ProCristal SuperClear) should always be rinsed several times in warm water before use and then rinsed again in cold water. To protect against unnecessary contamination, we recommend using a fleece bag or a sturdy filter basket with two layers of JBL Symec embedded in it.
In aquariums, activated carbon (e.g. JBL Carbomec activ, ultra) should only be used for a limited period of time to remove medication residues or unwanted discoloration. We recommend using it for 24-72 hours. Permanent filtration using activated carbon is not recommended, as useful substances such as protective colloids or nutrient carriers contained in modern aquarium fertilizers would also be removed.
