Within an aquaponics system is a delicate ecosystem composed of fish, bacteria, and plants. For everything to work perfectly, each part of the system must be balanced and healthy. Fish are required to be healthy to produce ammonia that is converted by the bacteria into nutrients for the plants.
Aquaponics systems can produce plants that can be harvested quickly because of the continuous amount of nutrients that the system provides to the plants. But before you can add the fish and more plants into the system, it is essential that the beneficial bacteria which produce nutrients for the plants is introduced and established.
Tilapia is one of the most popular fish species raised in aquaponics systems. They are known as one of the hardiest fish that can survive in a wide range of water conditions. Caring for tilapia is relatively easy because they are low maintenance. However, while they are easy to raise and ideal fish species for aquaponics, there are factors you need to know in raising tilapia to be successful.
Bacteria play a crucial role in aquaponics. They serve as the bridge that connects fish wastes to the plant fertilizer. Plants feed on nutrients supplied by the fish and decomposed fish food. However, before a plant can absorb these nutrients, they must be converted into nitrates. It is the bacteria that convert fish wastes into nitrates, which become food for the plants.
Many aquaponics beginners are often confused by the need for filtration in their aquaponics system. Do I need to add a biofilter? It is one of the frequently asked questions in aquaponics. To answer the question, we wrote this article to discuss biofilter, what it is, and do you need to have one in your aquaponics system.
