Water temperature affects not only the health of the fish, plants, and bacteria in an aquaponics system. It is also essential for the breakdown and uptake of nutrients and wastes. So in order to maintain a healthy aquaponics system, the water temperature must be kept in the range that is safe for the fish, plants, and bacteria growing in your aquaponics system.
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.
Your choice of grow media will significantly impact the cost of building and maintaining your aquaponics system. That's why this guide is written to help you understand what aquaponics grow media is, what are the available choices and what will work best for you.
