Water circulation method for fish tank

There are two ways to make the aquarium circulate water: the oxygen circulation system can play a role by planting aquatic plants, using animal and plant respiration and plant photosynthesis, or using air pumps to increase oxygen; Nitrogen circulation system needs to be composed of organic matter, ammonia, nitrates and nitrates. Plants can also be involved, but absorbed directly.

The water circulation of fish tank is divided into two parts, one is oxygen circulation and the other is nitrogen circulation. Fish need to breathe oxygen, which can be achieved by installing an oxygen pump, but if a circulation system is to be established, it is best to plant aquatic plants in a water tank, which can be released through photosynthesis. Nitrogen cycle needs nitrifying bacteria, which can transform ammonia nitrogen produced by manure decomposition into nitrate.
