Fish tank 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 […]
Water - the lifeblood of every aquaponic system
Water quality is everything. Get this right and everything else should follow very nicely!
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. Nitrification, photosynthesis and the toxicity of carbon dioxide and heavy metals are just some of the processes affected by this parameter. So what exactly is pH? pH is, in […]
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 fish tank temperature plays a fundamental role in determining how active our fish are. Fish, unlike mammals and birds, are unable to control their own body temperature. They are scientifically referred to as poikilothermic. Their metabolism reflects the temperature of the water in which they live. As a consequence, they will show a wide […]
Oxygen is the fuel of life and is critical to all fish ponds. Lack of oxygen is the number one killer of fish and characterised by fish seen gulping at the surface. It is essential for respiration and all fish will die if adequate levels are not maintained. All intensive growing on systems should really […]
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 […]
