Pond fish are finely balanced creatures. For maximum health you should be feeding them several times per day with carefully controlled amounts. This can be a time consuming activity and is impossible if you are away from the pond with work or on holiday. This auto feeder looks after all of this for you and is the most sophisticated feeder we have ever used. Automatic pond fish feeders are complicated pieces of machinery. If shortcuts are taken in the design process this can result in food jamming up the workings, which is a risk not worth taking if you value your fish. The 'pro' automatic feeder from velda of holland is the best feeder we have seen. It can handle all food types and can dispense up to 20 times per 24hrs.
