Ocean Free Pro Filter 3DM Rings 15-17mm - 2L

SKU 51046
  • 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.
