Ecological fish tank is a special filtration system assembled in fish tank, which has three functions: physical filtration, biological filtration and chemical filtration. It can effectively treat fish excrement, dead leaves of aquatic plants, fish food left by fish, etc. So as to keep the water quality in good condition. Without changing the water for a long time, it can achieve a good viewing effect. In fact, we can also make an ecological fish tank ourselves. Let's have a look.

1. Design the layout of the landscape, then sprinkle grass mud on the bottom of the tank, and put the selected landscape stones and sinking wood into the water.

2. Then there is the process of planting grass. Add lights and filters, and a simple primitive fish tank is completed. The process of planting grass is long, and it often takes 1-3 months to grow well.

3. If you want to do a good job in the original ecological fish tank and raise aquatic organisms, you must raise the water first. After the well-equipped fish tank is filled with water, it is necessary to put active nitrifying bacteria and water conditioner to remove harmful gases such as ammonia nitrogen in the water. Then, aquatic plants are cultivated with liquid fertilizer of aquatic plants. After 3-7 days, the water rose.

After the water rises, you can put the fish in the tank. The so-called fish in a jar is actually a trial culture to see if the water quality is up to standard. The trial rearing time also takes 3-7 days. If there is nothing unusual, you can officially raise aquatic animals.
