\u00a0 \u00a0 \u00a0 \u00a0 Fish farming is a dialog with water, and the filtration system is the \"translator\" of this dialog. The clarity of every drop of water is inseparable from the silent defense of the filter media - they are like a group of hard-working cleaners, silently decomposing toxins, intercepting impurities, just to make the home of the fish is always fresh. However, not all filter media are trustworthy, some in vain, some can in the smallest way to reverse the water quality. Today, we put aside the marketing rhetoric, with a scientific perspective to dismantle these \"water quality guardian\" of the true face, to help you take the wrong way, so that the fish pond really become a side of the ecological paradise of vitality.<\/span><\/p>\n

\u00a0 \u00a0 \u00a0 \u00a0Fish pond filtration system filter media selection and placement directly affect the water purification effect, the following is a comprehensive analysis of the professional point of view and recommendations:<\/span><\/p>\n

I. Filter material classification and core role<\/span><\/h3>\n
    \n
  1. \n

    \u200cPhysical filtration media<\/strong>\u200c<\/span><\/p>\n

      \n
    • \u200cBrush\/Rattan Cotton<\/strong>: Intercepts large particles of impurities, suitable for large water filtration in fish ponds.<\/span><\/li>\n
    • \u200cFilter Cotton (White Cotton, Magic Carpet)<\/strong>: Adsorbs fish poop, food debris and other tiny suspended matter, and needs to be cleaned regularly to avoid clogging.<\/span><\/li>\n
    • \u200cprotein cotton<\/strong>: Removes organic pigments and some chemical residues from the water.<\/span><\/li>\n<\/ul>\n<\/li>\n
    • \n

      \u200cBiochemical Filtration Filter Media<\/strong>\u200c<\/span><\/p>\n

        \n
      • \u200cBacteria House\/Ceramic Ring<\/strong>: The porous structure provides a huge surface area and is the main carrier for nitrifying bacteria, breaking down ammonia and nitrite.<\/span><\/li>\n
      • \u200cNanospheres\/Biochemical spheres<\/strong>: Enhances the contact area of water flow, promotes oxygen exchange, and improves the efficiency of bacteria cultivation.<\/span><\/li>\n
      • \u200cVolcanic stone \/ Maifan stone<\/strong>: Releases minerals, regulates water hardness and adsorbs harmful substances.<\/span><\/li>\n<\/ul>\n<\/li>\n
      • \n

        \u200cAuxiliary Function Filter Media<\/strong>\u200c<\/span><\/p>\n

          \n
        • \u200cgermicidal lamp<\/strong>: Kills algae and pathogenic microorganisms and inhibits algae outbreaks.<\/span><\/li>\n
        • \u200craw materials<\/strong>: Adsorbs residual chlorine and organic matter for a short period of time and needs to be replaced periodically.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
          \n
          \n
          \n
          \n
          \n
          \n
          \n
          <\/div>\n<\/div>\n<\/div>\n<\/div>\n
          \"\"<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
          \n
          \n
          \n
          \n

          II. Principles for screening effective filter media<\/span><\/h3>\n
            \n
          • \u200cPrefer high permeability filter media<\/strong>The water is also used in the water supply: e.g. ceramic rings, nano-balls, to ensure an even flow of water and sufficient dissolved oxygen.<\/span><\/li>\n
          • \u200cAvoid chalky products<\/strong>For example, poor quality \"corn cob\" filter media can clog the system and affect water quality.<\/span><\/li>\n
          • \u200cFunctional filter media on demand<\/strong>: such as strengthening the germicidal lamp when algae problems are prominent, with volcanic rocks when the water quality is acidic.<\/span><\/li>\n<\/ul>\n

            Third, the golden rule of filter placement<\/span><\/h3>\n
              \n
            1. \u200cPhysical front, biochemical back<\/strong>\u200c<\/span>
              \nThe direction of water flow should be as follows: filter cotton \u2192 brush \u2192 biochemical filter material (bacterial house, ceramic ring, etc.) \u2192 sterilization lamp, to avoid direct contamination of impurities biochemical filter material.<\/span><\/li>\n
            2. \u200cMounting height and spacing<\/strong>\u200c<\/span>\n
                \n
              • The top of the filter media is 10cm below the water surface, and the bottom is 25-30cm from the bottom of the pool to ensure full submersion and easy drainage.<\/span><\/li>\n
              • Biochemical filter media needs to be spread out or padded to avoid bagging and stacking to ensure that water flows through all pores.<\/span><\/li>\n<\/ul>\n<\/li>\n
              • \u200cWet and dry separation design<\/strong>\u200c<\/span>
                \nIn a drip box or crate, a wet\/dry separation zone is provided below the physical filtration layer to prevent water flow from washing away nitrifying bacteria.<\/span><\/li>\n
              • Biochemical filter media percentage \u2265 70%<\/strong>: Ensure sufficient space for bacteria cultivation, e.g. 1000L of water body needs at least 50L of bacterial house.<\/span><\/li>\n
              • \u200cPhysical filter media layered<\/strong>: First brush \u2192 white cotton \u2192 biochemical filter media, the direction of the water flow needs to be cleaned in reverse order.<\/span><\/li>\n<\/ol>\n

                \"\"<\/p>\n

                <\/h3>\n

                IV. Maintenance recommendations<\/span><\/h3>\n
                  \n
                • \u200cPhysical filter material<\/strong>: Clean 1-2 times a week to prevent clogging.<\/span><\/li>\n
                • \u200cBiochemical Filter Media<\/strong>: Lightly wash surface dirt quarterly to avoid destroying the flora.<\/span><\/li>\n
                • \u200cFunctional Filter Media<\/strong>: Such as activated carbon, sterilization lamps need to be replaced or power adjusted regularly according to the instructions.<\/span><\/li>\n<\/ul>\n

                  Through scientific matching and standardized placement, the effectiveness of the filter media can be maximized to achieve long-term stability of the water quality of the fish pond.<\/span><\/p>\n

                  V. Prioritization of the role of core filter media<\/span><\/h3>\n
                    \n
                  1. \n

                    \u200cBiochemical filter media (non-substitutable)<\/strong>\u200c<\/span><\/p>\n

                      \n
                    • \u200cBacteria House\/Ceramic Ring<\/strong>: The porous structure provides a huge surface area for the cultivation of bacteria and is the main habitat for nitrifying bacteria.<\/span><\/li>\n
                    • \u200cNano Balls\/Hollow Balls<\/strong>The honeycomb design enhances water flow uniformity and dissolved oxygen, which is suitable for high-density bacterial cultivation.<\/span><\/li>\n
                    • \u200cvolcanic rock<\/strong>: Aids in regulating water hardness and mineral release.<\/span><\/li>\n<\/ul>\n<\/li>\n
                    • \n

                      \u200cPhysical Filter Media (Basic Guarantee)<\/strong>\u200c<\/span><\/p>\n

                        \n
                      • \u200cBrush\/Rattan Cotton<\/strong>: Intercepts large particles of impurities and protects biochemical filter media from clogging.<\/span><\/li>\n
                      • \u200cFilter Cotton (Magic Carpet\/Cashmere Cotton)<\/strong>: It needs to be paired with wet\/dry separation design to avoid destroying the flora with frequent cleaning.<\/span><\/li>\n<\/ul>\n<\/li>\n
                      • \n

                        \u200cAuxiliary filter media (on demand)<\/strong>\u200c<\/span><\/p>\n

                          \n
                        • \u200cActivated carbon\/protein cotton<\/strong>: Adsorbs pigments or odors only for a short period of time and needs to be replaced periodically.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

                          \"\"<\/p>\n

                          \u00a0 \u00a0 \u00a0 \u00a0The ultimate romance of fish farming is to see how a pool of clear water reflects the rhythm of life. Behind this clarity is the day-to-day precision of the filter media: biochemical filters precipitate toxins like a hermit, physical filters kill dirt like a guardian, and auxiliary filters balance the delicate water quality like a mediator. Remember, the best filtration systems are not made of expensive materials, but rather by understanding the \"temperament\" of each filter media and letting them do their job. May your fish pond have both the rigor of science and the poetry of nature.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
