Hydrocarbon 2 is a granular activated
carbon designed specifically for the purification of water. It has an extremely
porous texture which makes it ideal for both fresh and saltwater aquariums and
does not leach phosphates into the water, which can cause outbreaks of algae.
This activated carbon absorbs both large and small molecular pollutants such as
the defense substances released into the water by both soft and stony corals and
will also pull out the water-yellowing tannic and humic compounds. After months
of use it also becomes a very active biological filtration community full of
beneficial bacteria and microorganisms. It can thus be used as a biological
nitrification and denitrification media, or to seed new aquariums with active
Use approximately 1.5 cups per 50 gallons of water. The entire contents will
treat 1600 gallons effectively. The desired amount of Hydrocarbon 2 should be
placed into a nylon filter bag,tied shut, and rinsed in a container of tap
water. Rinsing should be done a few times to minimize the amount of carbon dust
that is released into the tank. Once the bag has been rinsed it should be placed
in the filter in a place where the water will be directed right through it.
Carbon should be replaced once every 3 to 4 months.
