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 filtration.
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 water.
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 electronic charge.
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.
