  • The respiratory system

    The respiratory system Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills. The gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels, which give gills a bright red colour. Water taken in continuously through…

  • Module 5 – Setup

    Set Up NOTE:  This is probably the most important section in this course.  Sand is the most cost-effective filtration media anywhere! And therein lies a problem. You see, if you pour water containing organic matter onto sand, the organics will be trapped on the surface where they will eventually build up to the point where the…

  • Module 1 – Sand

    Sand No Sand – No Civilisation Sand is a benign substance that resides in the back of our minds. For most of us, it holds no more day-to-day interest than the rocks and roads – and the other physical aspects of our environment. We know that it exists but it hardly warrants a thought. But,…

  • 5.4.1. Nitrate in Depth

    Predicate All discussions of research papers on nitrate must be predicated with a caution. The 10 ppm of nitrate of the scientists, (the Hach test kit and the Lamotte test kit) is a 44 ppm test level of nitrate via the “normal” aquarium test kits (API aquarium test kit, the Seachem Multitest kit, the Sera…

  • Chlorine

    Chlorine You may not realise it but chlorine is classed as a plant micronutrient meaning that it is essential for the proper growth of plants. It is important to note though, that it is the ion (Cl‑) rather than the gas (Cl2) that is used by plants. In particular, chlorine is important for plant photosynthesis as it…
