  • FIGURING OUT WHEN AMMONIUM LEVELS ARE TOO HIGH

    FIGURING OUT WHEN AMMONIUM LEVELS ARE TOO HIGH… September 10, 2012 I had a minor freakout at the polytunnel today when on testing the ammonium levels were at 3mg/l. So why are the fish not even the teenyest bit dead? Here they all are – not one lost by the way since aquiring them… yet even…

  • Module 6 – Fish

    Fish If you’ve never kept fish before, you may be faintly hesitant at the prospect. Relax! When you operate authentic iAVs, you are engaging in freshwater aquaculture in its simplest and most cost-effective way. Freshwater aquaculture has been the subject of many doctorates…and its experts have published many substantial books. My point is that in…

  • 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…

  • Nitrification in rapid sand filter: phosphate limitation at low temperatures – unprocessed

    In winter 1995-1996 the RSF of AWS River-Lake Waterworks suffered from ammonium breakthrough. Research indicated that the nitrification was limited by stagnated growth of the nitrifying bacteria due to low phosphate concentrations at low temperatures (0-3°C). Phosphoric acid was dosed prior to the RSF (dose 35-50 μg PO43- -P.l-1) to stimulate bacteria growth. Two weeks after…
