\u00a0 \u00a0 \u00a0 \u00a0When the water thermometer breaks the red line of 30\u00b0C and the gill covers of the koi begin to open and close sharply, it is not only a challenge of the season, but also a moment of responsibility given to us by nature. Each koi is a flame in the water, and the light of their scales carries with it the expectations you have had year after year: perhaps the ink of the Showa Sanshiki finally emerging, or the fuller size of the Cha-cari. Managing the high temperatures is never just a matter of technique, but a deep understanding of the rhythms of life - we need to wake up earlier than the sun to monitor dissolved oxygen, be more agile than a rainstorm to regulate pH, and consistently stabilize water quality like the shadow of an old pine by the pool. This program will take you past the searing surface to the underlying logic of ecological balance in water bodies.<\/span><\/span><\/p>\n

<\/h3>\n

I. Temperature regulation system<\/span><\/h3>\n

1\u3001Physical cooling combinations<\/span><\/h4>\n
    \n
  • Shade mesh was selected from 70% shade rate black knitted mesh, 1.5 meters from the water surface to form an air insulation layer;<\/span><\/li>\n
  • A titanium coil is installed at the inlet of the filtration bin to connect to the underground water circulation system (a temperature control valve is required);<\/span><\/li>\n
  • Fogging sprinklers are turned on from 14:00 to 16:00 daily to cool down using the principle of heat absorption by evaporation of water vapor.<\/span><\/li>\n<\/ul>\n

    2. Biological cooling strategies<\/span><\/h3>\n
      \n
    • Climbing plants such as Campsis grandiflora\/grapevine are planted around the pool to create ecological shade;<\/span><\/li>\n
    • Water lilies with 20% area floating on the water surface have a root system that can absorb excess nutrient salts.<\/span><\/li>\n<\/ul>\n

      \"\"<\/p>\n

      II. Precision feeding management<\/span><\/h3>\n

      1. Adjustment of feed formula<\/span><\/h4>\n
        \n
      • Protein content reduced to 28%-32% (formerly 35%-40%)<\/span><\/li>\n
      • Add 0.5% Spirulina Powder to enhance the anti-stress ability<\/span><\/li>\n
      • Switch to 3mm slow-sinking feeds to reduce deterioration from surface exposure<\/span><\/li>\n<\/ul>\n

        2\u3001Feeding monitoring points<\/span><\/h4>\n
          \n
        • Use infrared thermometer gun to detect fish gill temperature >33\u2103 immediately stop feeding<\/span><\/li>\n
        • Setting up automatic baiting machine to feed in 6 times (a single amount will not be eaten in more than 3 minutes)<\/span><\/li>\n<\/ul>\n

          III. Water quality crisis management<\/span><\/h3>\n

          1. Algae outbreak tertiary response<\/span><\/h4>\n
            \n
          • Primary: Installation of 55w nano aerator discs to increase water disturbance<\/span><\/li>\n
          • Intermediate: add potassium persulfate complex salt at 5ml per ton of water<\/span><\/li>\n
          • Ultimate: introduction of 200 Rhodeus sinensis to establish biological control<\/span><\/li>\n<\/ul>\n

            2. Dissolved Oxygen Assurance Program<\/span><\/h4>\n
              \n
            • Venturi injector between main pool and filter bin<\/span><\/li>\n
            • Increase air pumps from 3-5 a.m. (when air pressure is lowest)<\/span><\/li>\n<\/ul>\n

              IV. Filtration system enhancement<\/span><\/h3>\n
                \n
              • Mechanical filtration upgrade<\/span><\/li>\n<\/ul>\n
                  \n
                • The pre-compartment was changed to use 50ppi pore size biochemical cotton to intercept fine algae<\/span><\/li>\n
                • Addition of a cyclone settler as a first physical filtration step<\/span><\/li>\n<\/ul>\n
                    \n
                  • Maintenance of biochemical systems<\/span><\/li>\n<\/ul>\n
                      \n
                    • Monthly rinsing of K1 filter media with raw pool water (no tap water rinsing)<\/span><\/li>\n
                    • Volcanic stone layer (thickness \u2265 15cm) in the drip box<\/span><\/li>\n<\/ul>\n
                        \n
                      • Equipment maintenance calendar<\/span><\/li>\n<\/ul>\n
                          \n
                        • Every Monday: Check pump bearing lubrication<\/span><\/li>\n
                        • 15th of the month: Testing of UV lamp irradiation intensity<\/span><\/li>\n
                        • Before the storm: check lightning grounding devices<\/span><\/li>\n<\/ul>\n

                          \"\"<\/p>\n

                          \u00a0 \u00a0 \u00a0 \u00a0 When the water temperature is 28-32\u2103, the metabolism of koi is vigorous, and the intake can reach 3%-5% of body weight. feeding high-protein feed (crude protein \u226535%) with small amount of multi-food (4-6 times a day), the weight gain can reach 2-3cm per month. it is recommended to add Spirulina (5%) to enhance the color of the body, and with Vitamin C (200mg per kg of feed) to enhance the immune system. Vitamin C (200mg per kilogram of feed) to enhance immunity.<\/span><\/h3>\n
