OceanFree Pro Series Filter Medium 3DM – Rings

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
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. Ocean Free 3DM Pro-Filter Medium introduces the concept of bio-membrane flaking that minimizes the clogging of cavities and micro tunnels
Longer Water Retention Time: Ocean Free 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: used Ocean free 3DM Pro-Filter Medium can also be reused for horticulture purposes due to high mineral content and non-toxicity

Caution:
Increase OceanFree 3DM pro-filter medium’s effectiveness with adequate mechanical filtration (E.g. coarse wool, bio-mat, etc. To filter off solid waste at water inlet to prevent clogging of micro-tunnels. Do not rinse batteries-colonized OF 3DM pro-filter media with tap/chlorination water. Use old tank water instead. Exercise extreme caution when using medication especially antibiotics to prevent elimination of beneficial bacteria. Do not use in small chamber with exposed UV sterilizers
