Industry experience in fish pond filtration and landscape water treatment; our company's eco-liquid developed to decompose fish waste and leftover feed can establish an artificial ecological chain in water; this system utilizes principles from biological engineering and physics to design an excellent biological filtration and purification recycling system, ensuring the fish pond water remains clear, transparent, free of turbidity and odor, providing a favorable "living water" ecological environment for the fish, and is currently a scientific water treatment technology for fish farming.

How to raise fish starts with nurturing the water
When changing water, retain some of the old water in the aquarium. The water used for the fish should be exposed to sunlight for 24 to 72 hours. The new water should be similar in temperature to the old water. Add a little salt to the new water to enhance the fish's disease resistance. Goldfish should not be overfed; uneaten food can spoil and cause illness in the fish, as well as degrade water quality. Method for changing goldfish water.

The principle of a landscape fish pond that requires no water change year-round
Changzhou Hongbo Environmental Protection Engineering Co., Ltd.'s fish pond biological filtration purification system can maintain crystal-clear water and the need for water replacement throughout the year without damaging the original landscape fish pond. The principle is as follows:
The landscape fish pond biological filtration system of Changzhou Hongbo Environmental Protection Engineering Co., Ltd. is mainly composed of a circulating pipeline, submersible pump, biological sand, and ecological liquid, forming a biological purification and physical filtration system. The circulating pipeline and pump function to circulate the water body and increase oxygen; the biological sand, soaked and cultivated in the ecological liquid, forms a biological filter bed at the bottom of the landscape pool. Through the pump network system, the waste products, leftover feed, and nutrients (including organic matter) of the fish are slowly circulated, crushed, and absorbed into the biological sand layer, where they are decomposed and oxidized by the biological sand, producing volatile nitrogen gas and water. This also generates autotrophic beneficial bacteria, absorbing sunlight to inhibit algae and moss; it eliminates the accumulation of substances that degrade water quality, maintaining the clarity of the water.
Nutrients (including organics) are drawn into the bio-sand layer through the pump network system, then undergo ecological liquid oxidation and decomposition to produce NO3 (salt). Anaerobic denitrification follows, yielding NO2 and NH4+. These are further decomposed by aerobic bacteria, resulting in N2 and H2O, which are then volatilized. (Autotrophic bacteria absorb sunlight to inhibit algae and mosses, etc.)
Fishkeepers know that frequent water changes affect fish, and koi fish often face new water quality, making them prone to illness, especially when the water temperature difference exceeds 6 degrees, which can directly harm koi fish. After years of research, the biological pond purification system equipment has taken into account various factors and summed up the best methods and experience. This system is favored by fishkeeping enthusiasts, bringing a true revolution to the fishkeeping industry, and this is the power of science and the progress of society.
