"Active filter carbon, ready to use in set for CP i-range • Activated carbon specially designed for pH 8. • 100 % phosphate-free. • Absorbed materials not re-released. • pH-neutral and neutral conductivity. • Packed in fleece bag, ready to use. • Also suitable for pH levels of about 8 in Malawi and Tanganyika aquariums. • Can be used with CPi60, but not recommended as sole filter media Product description JBL Carbomec ultra is an activated carbon in pellet form with extremely high absorbtion capacity. lt is particularly well suited for the long-term removal of discolouration and high molecular organic pollutants from saltwateraquariums. In freshwater aquariums, JBL Tip: JBL Carbomec ultra should only be used for a very short length of time (max. 2-3 days) to remove residual medication or other harmful substances in freshwater aquariums. In freshwater aquariums, JBL Carbomec ultra should not be permanently used as a filter substance as beneficial substances such as protective colloids or nutrients found in modern aquarium fertilizers (JBL Ferropol) will also be absorbed. Use Before using, rinse the carbon several times in warm water, then in cold water. Do not open the fleece bag. Sandwich the fleece bag of carbon between two layers of JBL Symec in the filter to prevent unnecessary soiling. Problem solutions Measures to eliminate pesticides and herbicides from tap water: 1. By installing the JBL Reverse Osmosis unit, 95% of all herbicides and pesticides are removed. 2. If the tap water is also passed through JBL Filter Carbon before it is used, pesticides and herbicides are almost completely eliminated. Measures to eliminate pesticides and herbicides from aquarium water: 1. Depending on the pH-levels, JBL Active Carbon is used: A.) For pH-levels up to 7,5 JBL Carbomec active is used. B.) For pH-levels over 7,5 JBL Carbomec ultra is used.
