Fish Pond Cleaning｜Physical + biochemical filtration double maintenance, 30 minutes to restore the ecological balance of water quality!

      Experimental proof: incorrectly cleaned filtration system, fish pond ammonia nitrogen values spiked 3001 TP3T.
According to the statistics of "Ornamental Fish Ecological Conservation Report", more than 65% ornamental fish death cases are directly related to improper cleaning! Physical filtration and biochemical filtration "functional zoning", water temperature fluctuations on the fish "invisible kill", nitrifying bacteria "colonization of the golden period" - every detail is related to the survival of the fish tank. -Every detail has a bearing on the survival of the fish tank.
This article combines ten years of experience in aquatic engineers, with a tool table + three-stage cleaning method, to bring you low-cost realization of the fish pond water quality "reverse"!

I. Preparation before cleaning

1. ‌Drainage and Fishing‌

   • Start by pumping the pond to 1/3 of the water level to facilitate the fish-fishing operation.
   • Fish are fished using oxygenating equipment to ensure survival and transferred to temporary containers for temporary storage.
   • 

2. ‌Tool Preparation‌

   • Prepare a high-pressure water gun, a cleaning brush, a container (for the filter media), raw pool water or new water of the same temperature.

Second, the filter system cleaning steps

(1) Physical filter layer cleaning

• ‌Filter Wool / Filter Cartridge‌
  • Remove the filter wool or volcanic stone filter cartridge and rinse the surface with a high-pressure water gun to remove any adhering impurities and algae.
  • Light rinsing is sufficient, avoid rubbing vigorously to cause structural damage to the filter media, affecting the subsequent filtration effect.
  • Use raw fish pond water for rinsing to minimize loss of beneficial bacteria.

(2) Biochemical filter media cleaning

• ‌Biochemical cotton/ceramic ring/biostone‌
  • The biochemical cotton is simply pinched and washed gently in water to retain some of the beneficial flora.
  • Ceramic rings, biostones, etc. do not need to be cleaned frequently, 1-2 times per year; when cleaning, lightly brush the surface dirt to avoid damaging the internal bacterial film.

(3) Overall cleaning of the filter compartment

• Open the filter bin lid and remove any sludge and debris deposited at the bottom.
• Flush the bin walls and pipes with a high-pressure water gun to ensure there are no blockages.
• 

III. Precautions

1. ‌Protection of nitrifying bacteria‌

   • Avoid cleaning all the filter media at once, batch operation is recommended to maintain system stability.
   • After the biochemical filter media is cleaned, nitrifying bacterial preparations (e.g. Chilofen active nitrifying bacteria) can be added to accelerate the recovery of the flora.

2. ‌Cleaning frequency‌

   • Physical filtration layers (e.g., filter wool) are inspected weekly and cleaned or replaced depending on the degree of soiling.
   • The biochemical filter media is cleaned locally every 3-6 months and thoroughly cleaned no more than 2 times throughout the year.

3. ‌Equipment Maintenance‌

   • Regularly check the circulating water pump, ultraviolet sterilizer and other equipment to ensure that the water flow and sterilization function is normal.

IV. Supporting measures

• ‌Water Quality Maintenance‌
  • It is recommended to change no more than 1/3 of the water after cleaning to avoid fluctuating water temperature affecting the health of the fish.
  • It can be used with microbial preparations (e.g. Spore Pioneer, Double Reformer Pioneer) to decompose organic matter and prevent water quality deterioration.

       By using the above methods, the filtration system can be effectively cleaned and the ecological balance of the fish pond can be maintained.

     "Fish first, water first, water protection first, bacteria first!"Scientific maintenance of the filtration system not only extends the life of the filter media, but also creates a healthy ecosystem for the fish. At the end of the article comes a free "fish pond water quality self-test form", regular monitoring of nitrite, pH and other key indicators, so that hidden dangers have no hiding place!
