Pump and Filter required

[Gordon54]

Hi we have a pond which is 11ft long, 5ft wide and 4ft deep approximately. Our pond tapers as it gets deeper and so we reckon it is about 2/3 of the capacity it would be if it was those dimensions without the taper. So I have calculated (maybe wrongly) that it takes between 4000 and 5000 litres of water. We need to get a filter and a pump for the pond and just need advice about what sort of pump/filter we would need. We are planning on having goldfish in the pond if that makes a difference. Any advice would be greatly appreciated.

Have you considered a bog filter? Seem like that should be cheaper than a store bought unit and less work for excellent results in the long run.
