Humin Elixier is an water conditioner with extracts of oak bark, alder cones and catappa leaf. Dennerle Humin Elixier makes it especially easy to acclimatise and care for all fish from black water regions, such as discus, neons, scalars, dwarf cichlids and long-whiskered catfish. The water conditions like those in nature reduce stress. Humic and tannic substances strengthen the mucous membrane and therefore reduce the risk of skin diseases. Humin Elixir increases spawning and hatching rates. Healthy fish that feel good display their vibrant colouring in all its glory. Particular advantage: Humin Elixir contains humic and tannic substances that only have a weak colouring effect or none at all. In contrast with many conventional peat products the water does not take on an unsightly brown colour. Guaranteed free from phosphoric acid and hydrochloric acid.
