Your pond fish and koi will receive vitamins through the food you feed them and through the natural nutrition present in your pond. As with people the vitamin supply is only sufficient when a balanced diet is available. The same also applies to your pond dwellers, and therefore it is advisable to administer an extra dose of vitamins at least once a week.
The most efficient method is to drip the vitamin concentrate JBL Atvitol onto the food, shortly before it is fed to the fish. If your fish show symptoms of disease, the vitamin cure becomes the most important measure in addition to the addition of medicines. Medications only have an effect on pathogens, whereas vitamins strengthen the fish’s resistance to disease and help it become healthy again.
