How
to choose the best carbon filter for your fish tanks
The filtration
system
of your fish tank, mean the difference between
a healthy and a not so healthy tank. The fish in your tank
must have
the proper environment to remain healthy and provide you with hours of
enjoyment.
A carbon filter for
fish tanks is one of the most commonly used type
of filters. You’ll need to choose your carbon
filter for fish tanks
based upon the size of your tank, the amount of water in your tank, and
the type of fish in your tanks.
Carbon filters are
made
from gas activated carbon. Granular
activated carbon is made from coal, heated in the presence of steam at
very high heat. This process causes the carbon to develop huge numbers
of tiny pores, which trap wastes at the molecular levels by adsorption
and ion exchange. It removes heavy metals and organic molecules through
a process known as molecular sieving.
The best GAC for
filtering water is macro-porous (having larger
pores). A good macro-porous activated carbon feels light and floats
when initially wet.
You should buy only
carbons made by reputable aquarium supply
companies. These carbon filters have been acid washed during
manufacture to minimize ash content. Carbons low in ash reduces the
chance of pH shifts. It’s a good idea to
pre-soak your carbon filters
in water for a few weeks before you use the carbon filter for fish
tanks. This eliminates undesirable high phosphate levels.
A carbon
filter for fish tanks is cheap enough to use liberally.
Always wash your carbon before use to remove the dust that accumulates
during shipment. Smaller amounts changed more regularly seem to work
best. You probably want to experiment, but 1/2 cup per 20
gallons
water, changed monthly is a good place to start.
Carbon filter
for fish
tanks is an excellent, cheap, and effective
filtration method for all tanks. The potential benefits of carbon
filter for fish tanks is enough that on whole you will be better off
using it. If trace element depletion is a concern, use trace
element
supplements with the activated carbon.
