JBL ProPond All Season Fish Food provides a balanced, basic diet for koi and other pond fish and is best fed during the spring, summer and autumn. ProPond All Seasons Food is a floating stick, available in 2 sizes; 8mm and 14mm to suit a range of fish sizes. JBL ProPond All Seasons has been optimised to a 3:1 protein/fat ratio in accordance with the NEO index. The NEO index literally means: Natural Energy Optimised nutrition. Behind this lies the ratio of proteins to fats in the food. Looking at the season alone, the fish would only need half as much protein in winter (2:1) as in summer (4:1). But because not only the season (water temperature), but also the size and age of the fish, and food function play determining roles, the NEO index has been developed to deal with all these factors in one.
