KORDON BIO·MECH has proven extremely effective in promoting
biological filtration, because it is an exceptionally good base for
nitrifying bacteria. Constructed of a porous ceramic stoneware; Bio·Mech
possesses a positive electronic change, so slight it is generally
unnoticed, which attracts the nitrifying bacteria needed for biological
The open ring or "noodle" shape, combined with the porous nature of
the stoneware, provide a tremendous surface area which can support a
population of billions of bacteria in a relatively small filter
compartment area. The colonization of Bio·Mech filter rings by
nitrifying bacteria is extremely important to aquarium and pond keeping.
These bacteria are beneficial in removing toxic ammonia and nitrite
from the water. Biological filtration is the most effective natural way
to remove these stressful and lethal substances from aquarium and pond
The extent of biological filtration is dependent upon the amount of
dissolved oxygen available to the bacteria. Because the inlet area of a
filter contains the highest level of dissolved oxygen, Bio·Mech is most
effective when used in the inlet area or as a prefilter. The open
design of Bio·Mech allows water to circulate throughout, bringing the
necessary oxygen to the bacteria. The tendency of BIO·MECH to diffuse or
spread water through the entire filter compartment is also useful,
because this prevents "channeling" (water following the course of least
resistance) and makes filter materials located in the subsequent water
flow more effective. Bio·Mech resists clogging by slightly and
continually rotating as the water flow passes through and around the
rings. The ring shape gives Bio·Mech a major advantage over other filter
materials such as those in pad or ball form, which do not freely rotate
as they collect debris.
Bio·Mech is a very effective mechanical filtering material,
especially in coarse screening. Mechanically the filter rings break up
the water flow through the filter forcing the water flow to spread
evenly without channeling or bypassing or clogging the filter materials.
Bio·Mech rings regain and entrap large particles of debris which are
worn down by water turbulence and bacterial action. The rotation of the
Bio·Mech rings keeps the debris moving and prevents it from clogging the
filter. The rotation also constantly changes the form and position of
the debris, constantly moving it along the surfaces where the nitrifying
bacteria consume the organic waste materials. By retaining larger
debris particles within the Bio·Mech filter area, Bio·Mech helps all
subsequent filter materials, such as finer mechanical screens, from
becoming prematurely saturated or clogged.
The technical qualities of BIO·MECH that are important considerations in filtration are:
- durable, long lasting, reusable and easily maintained for biological and mechanical water filtration.
- easily sterilized and reused.
- high percentage of void space and low resistance to water flow (low pressure drop).
- irregular shape prevents packing. Its shape prevents locking of the filter materials together and reduction of water flow.
- large active surface exposed per unit volume (high surface area per cubic measure).
- good internal liquid distribution characteristics.
- suitably shaped to product turbulent contact between water phases.
- large number of interstitial transfer points per unit volume.
- microscopically porous surfaces make them a superior solid home for beneficial nitrifying bacteria.
Kordon Bio·Mech is durable, long lasting, and stable indefinitely.
It requires no special handling procedures. Bio·Mech requires only a
periodic rinsing to remain effective. Washing and treating with soap,
household cleansers, and cleaning chemicals do not interfere with its
Bio·Mech does not affect, and is not affected by water quality,
medications, or water conditioners. Bio·Mech is nontoxic and harmless to
plants, fishes and invertebrates. This product is safe for use in all
types of aquaria and ponds.
