One of the benefits of having an aquaponics system is that there is no need for synthetic fertilizers. The system uses fish, which will be the source of nutrients for the plants. Left alone, the waste produced by fish into the water tanks leads to an unhealthy aquatic environment. However, aquaponics leverages this waste by using the plants to filter out toxins. As nutrients from water get absorbed by plants, the water then becomes purified, clean, and safe enough to return to the fish tank.
