Revolutionary Aquarium Biological Filter Medium

OF® 3DM 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.

It’s recommended for aquarist seeking the ultimate aquarium 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 OF® 3DM Pro-Filter Medium 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 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 OF 3DM Pro-Filter Medium to be in the range of 2550m² / litre, far surpassing other biological mediums in the market.
pH Neutral. pH-inert material does not modify pH; suitable for soft-water, brackish, hard-water and marine fish.
Flaking of Bio-membrane. Fine exo-skeletal deposits and organic particulates will accumulate and reduce your filter medium’s effective surface area over time. OF 3DM Pro-Filter Medium introduces the concept of bio-membrane flaking that minimizes the clogging of cavities and micro-tunnels.
Longer Water Retention Time. OF® 3DM Pro-Filter Medium increases the passage time of water within the filter with help from the cavities and micro-tunnels. This will greatly upgrade the capabilities of your biological filter by prolonging the water treatment period.
Environmentally Friendly. OF® 3DM Pro-Filter Medium can also be reused for horticulture purposes due to high mineral content and non-toxicity.
