Nitrite is a simple chemical made up of two atoms of oxygen combined with one of nitrogen, hence NO2. It can be represented simply by Diagram 1 above. Fish do not directly produce nitrite. Rather it is primarily an end product of the first stage of nitrification that occurs within a biofilter. Fish constantly excrete […]
Water - the lifeblood of every aquaponic system
Water quality is everything. Get this right and everything else should follow very nicely! Better water quality almost always means better fish. It really is the lifeblood of aquaponics.
What is pH? As fish keepers we cannot afford to ignore pH. It has a profound affect on an enormous range of biological and chemical processes that occur within a fish tank. Nitrification, photosynthesis and the toxicity of ammonia and carbon dioxide and heavy metals are just some of the processes affected by pH levels. […]
Nitrate is a key element in all aquaponic systems as it’s formation, and assimilation, is vital for the health of both fish and plants. Chemically speaking, nitrate exists as NO3–. This means that one nitrogen atom is coupled to three nitrogen atoms. It also has a single negative charge. that influences how it is transported. […]
The water temperature of your pond, or aquarium, plays a fundamental role in determining how active fish are. This in turns will have both a direct and an indirect affect on water quality. Fish, unlike mammals and birds, are unable to control their own body temperature. They are scientifically referred to as poikilothermic. That is, […]
Novice fish keepers often ask the question, do fish need oxygen? It is not long before they learn that the answer is an emphatic yes. Oxygen is often described as the fuel of life and, as such, it is critical to all aquaponic systems. It is an essential ingredient of respiration , a process that […]
A good understanding of ammonia is a great basis for getting the most out of any aquaponic system. It is a key element in ensuring healthy fish and plants. Ammonia is highly toxic and consequently needs to be removed. If allowed to accumulate in a fish tank it will certainly cause undue stress, encourage disease […]
