  9. Ocean Free 3DM Rings Pro-Filter Medium 0.5 Litre (In Net Bag)

    Ocean Free Pro-Filter Medium is a revolutionary mineral based beneficial-bacteria medium that incorporates the most advanced heating and multi-staged manufacturing techniques and technology to create this super macro-porous and tough biological filter medium. Features:

    * Improves water quality: Perfect medium to establish Nitrogen Cycle and help eliminate ammonia, Nitrite, Nitrate and to prevent other poor-water quality related diseases.

    * Tough, and Macro-Porous: Advanced manufacturing and high temperature processes has given Ocean Free 3DM Pro-Filter Media their distinctive lightweight, tough and porous structure. Within the tough exterior lies 3 dimensional cavities of various spatial apertures (micro, medium and large cavities) all interlinked by micro tunnels.

    * Ideal Bacteria Conditions: Continuous cavities and interlinked micro-tunnels increase the overall effective surface area of, and create ideal conditions for billions of Aerobic and Anaerobic bacteria (under "ideal bacteria conditions". Maybe we change "necessary for Nitrogen cycle" to "required for the completion of the Nitrogen Cycle") within a single filter medium. The result is a faster Bacteria colonization time, stable and longer bacteria life span.

    * Largest Effective Surface Area: BET Method surface area analysis has determined the effective surface area of Ocean Free 3DM Pro-Filter Medium to be in the range of 35,000M2 - 72,000M2 / litre, far surpassing virtually all other biological medium in the market.
