Is a concentrate solution formulated for Discus and all other freshwater tropical fish. It contains iodine, magnesium and a complete vitamin B complex (B1, B2,B6, B12) ideal for increasing vitality, stimulating appetite and reproduction and promoting the fish’s natural colour. As aquarium water poor in iodine provokes thyroid problems and magnesium strengthens and reinforces the bone structure preventing stunted growth, it is therefore essential to maintain these minerals at a constant level in the aquarium. As DISCUS ELIXIR is a liquid it is easily absorbed and constant use of this product ensures these minerals and other elements vital for Discus and all other tropical fish are maintained in the water. This product promotes microorganisms in the biological filter.
