1. Physical filtration: This is a filtration method that uses various filter materials or additives to remove dust, colloid, suspended matter, leaves, etc. To keep the water transparent. The standard device is the method of passing water through the filter pond from bottom to top, which will be introduced in the amateur ornamental fish pond later.
2. Chemical filtration: This is a filtration method that uses filter materials to remove various ionic compounds or odors that are harmful to fish dissolved in water through absorption. Commonly used filter materials are activated carbon, zeolite, Refesh, scale king (medical stone) and so on. Others include ion exchange resin, manganese zeolite, etc. However, the use of these materials requires special filtering devices.
3. Biological filtration: The equipment of our fish pond biological purification system is different from the traditional mechanical circulating water filtration in fish ponds. It uses a combination of physics and biology to purify the fish pond, which not only purifies the fish pond, but also allows the water body to circulate and ventilate itself, giving the fish a good natural ecological environment. After nearly ten years of practice, it is the most advanced fish pond purification and filtration technology in China.
4. Plant filtration: the harmful factors produced by fish excreta are called the filtration mode absorbed by plants in water.
Available aquatic plants are duckweed and calamus. Duckweed should be placed on the front filter, and calamus should be planted in the waterway between the filter and the pool. Acorus gramineus can not only filter plants, but also absorb iron ions.
Koi fish fish pond biological filtration purification, really do not need to change water all year round, the water quality is still crystal clear; Mainly research and develop the microbial purification system technology of ornamental fish ponds (national patent biofiltration method). At the same time, the garden aquarium in Fu Jia involves various fields of garden gardening, balcony rockery fish ponds and other projects.
