Pond pressure filter without UVC. This pressure filter has all of the features that has made the Fish Mate range a bestseller but is \'bio\' only. Run with a 9,000lph pump it can be used in a pond sized at 9,000 litres (2,000 gallons). At Pondkeeper we often get asked questions by our customers who are putting together a project and want advice. This is what we would recommend to any customer who has owned a pond for a while that requires a new filter but already have a UV and pump still running. In such cases this product like comes in handy! NOTE: UVC bulb included.
