TWO LITTLE FISHIES HydroCarbon 2 GAC
Directions: Use approximately 250 ml (1/2 cup) of HydroCarbon 2 G.A.C. per 50 gallons. Entire contents will effectively treat 200 gallons. Pour the required quantity into a polyester or nylon filter bag. Carry the dry bag of HydroCarbon 2 G.A.C. outdoors and also bring a container partially filled with tap water that will be used to rinse it. When outside, immerse the closed bag into the container of water. The porous carbon sizzles a sit becomes hydrated, and carbon dust is released into the air and rinsing water. Do not breathe the dust! Shake the bag underwater and lift and immerse it again repeatedly in order to wash out most of the fine dust. The black water produced is safe to pour down a drain, or into the soil outdoors.
Locating the HydroCarbon: For the most rapid removal of water staining organic and other pollutants, place the bag of pre-rinsed HydroCarbon 2 G.A.C. in a filter chamber where water flow is directed through it. Use filter floss before the bag to trap fine particulate matter that could clog the bag. May be used without a filter bag in external powerfilters by installing filter floss above and beneath the carbon to retain it. Important: When it is being used in a high-flow filter chamber, be sure to close the bag so that the carbon is kept tightly packed. This will prevent the granules from tumbling, which could liberate carbon dust into the water. HydroCarbon 2 G.A.C. can also be used passively, without filter floss, by locating it in a filter chamber in such a way that water flows over and through the bag but is not forced through it exclusively. Continuous use in this passive manner still effectively prevents the accumulation of yellowing substances, keeping the water sparkling crystal clear. Replace with new HydroCarbon 2 G.A.C. as needed to maintain the colorless water. Normally effective for several months.
Important: Keep this container tightly closed to prevent air pollution from being adsorbed. Do not use HydroCarbon 2 G.A.C. when medicating the aquarium. Can be used to remove medications from the water when treatment is complete, but should be discarded afterwards.
Ozone: HydroCarbon 2 G.A.C. effectively removes ozone when located at the water stream exiting an ozone contact chamber such as a protein skimmer or oxygen reactor. When used for this purpose it should be changed once per month.
