Aquaponics bacteria form a diverse and complex community of microorganisms unique to each individual system. the nitrogen cycle is a complex web of relationships formed according to the local environmental conditions and food supply. there are two main groups of bacteria that are of prime importance. autotrophic ammonia oxidising bacteria.. Following this logical thread, in aquaponic gardening we are bacteria farmers. the animals that fire our systems are our fish, but the engine of the system is the nitrifying bacteria that convert the fish waste from poisonous ammonia to nurturing nitrates.. The bacteria in an aquaponic system are housed on a biofilter, which is a fancy name for anything that has a large amount of surface area relative to volume for the bacteria to colonize. there are many materials that aquaponic growers use as biofilters, including volcanic gravel, expanded clay, commercial plastic biofilter balls, bottle caps, or mesh materials..
Instead of discharging water, aquaponics uses the plants, naturally occurring bacteria, and the media in which they grow in to clean and purify the water, after which it is returned to the fish tank. this water can be reused indefinitely and will only need to be topped-off when it is lost through transpiration from the plants and evaporation.. The water quality and bacteria online aquaponics class is part of the flourish farm aquaponic online course. this class will cover critical water quality parameters to monitor and how to adjust them so that you are maintaining the best water quality for your fish, plants and bacteria..
