 There are two types on pond fish feeders. The first type of machine is the automated pond fish feeder. You load up with the necessary food and it will dispense the food at a regular interval to the pond. These offer a great way to ensure your pond fish get fed at regular intervals with the correct amount of food. It also takes away the need to remember to feed your fish or when you go on holidays to get someone in to look after feeding your pond fish.
The other type of pond feeder is the feeding ring. This is a very cheap and simple device which is a plastic ring that floats on the surface of the water. You put the food in the ring which stops it from floating off into the filter or not being used. These are a cheap device which assists in keeping your pond cleaner and clearer. |
