After the strains of winter your koi are exhausted and need sufficient reserves to cope with the changing conditions of spring. Healthy ingredients, such as spirulina, shrimps and salmon form the basis of a protein/fat ratio of 3:1, as recommended by experts, which is known in the JBL ProPond range as NEO index.
That’s why JBL ProPond Spring is the perfect, professional nutrition for koi in water temperatures between 10 and 20 °C. It is therefore clear that, in order to provide them with an adequate food with the right protein/fat ratio and the appropriate ingredients, we need to assess our koi for the season, water temperature, size, age and living conditions. The JBL ProPond concept was designed precisely for that!
