An aquaponics system is considered functional and established once system cycling is done, the nitrifying bacteria is established, and there are no signs of fish stress and plants' nutrient deficiencies. One crucial factor that has a vital role in aquaponics system cycling is nitrate.
One of the questions an aquaponics beginner often asks in planning to build their own aquaponics system is, what is the fish to plant ratio in aquaponics? There are determined ratios between the biofilter size, planting density, and fish stocking density for aquaponics. It is challenging to operate beyond these determined ratios without risking disastrous consequences for the entire aquaponics ecosystem.
