A home-scale aquaponics system

Aquaponics is a sustainable and innovative method of growing plants and raising fish simultaneously. It combines the principles of aquaculture (fish farming) with hydroponics (growing plants in water). By harnessing the natural symbiotic relationship between fish and plants, aquaponics creates a closed-loop system where waste from the fish provides nutrients for the plants, and the plants filter the water for the fish.

Understanding the Basics of Aquaponics

In order to set up and manage a home-scale aquaponics system, it is crucial to understand the basic principles. The heart of the system lies in the fish tank, which serves as a nutrient source for the plants. Fish waste produces ammonia, which is converted into nitrates by beneficial bacteria.
