Ammonia in aquaponics systems is important to understand and control. This video takes a good look at the effects of ammonia in aquaponics gardens and how it is actually two separate compounds, one is toxic and the other is not a real problem for the plants and fish. Bright Agrotech takes a very careful look at the production and the way the ammonia is being oxidized in the aquarium system of the aquaponics system.
Take your time with this video, the information is very important, for people with an aquaponic system but also aquarists who are running standard filtration as well. Nate Storey provides a clear view of the two compounds ammonia and ammonium and how they are interrelated with pH and the fish and plants.
Ammonia in Aquaponics is dangerous
Ammonia is found in aquaponic systems that have pH above 7.0. Ammonia in aquaponics systems will hurt a lot of live organisms such as fish, bacteria and even the plants in the grow bed. The suggestion is to drop the pH to much lower than suggested by most aquaponic people.
His suggestion is to run the system in a pH of about 6.0. That may stress some of the fish. But at least it will drop the ammonia in aquaponics systems you may be operating. But the real goal, is to make sure there is minimal wastes and no ammonia/ammonium, but rather the only compound found is nitrate instead.
