The GPF-30000 is a pressure filter with built-in 55w UV-C unit.
 
The filter has several functions that are not obvious for a pressure filter.
• It can be easily cleaned by backwash and a cleaning crank.
• The filter does not need to be opened to be cleaned.
• It is equipped with a built-in UV-C of 55W.
• Easy to control that the UV-C lamp is lit. A blue light on top of the container indicates that the lamp is lit.
• The filter can be buried to be as "invisible" as possible in your garden, and can be mounted above or below water level in the pond.

 
The GPF-30000 has both larger and more sponges than the smaller models.
Through the newly developed cleaning function where you turn a crank instead of pulling a handle, cleaning becomes much easier.
Instead of the sponges being compressed, they are scraped off, which means more dirt can be flushed out of the filter.
The wash also drives water backwards through the sponges, so cleaning goes both deep and to the surface.
Filtration advice
Take note that although each filtration system is rated for a specific pond literage, we calculate filtration differently in practice. Size matters, but what matters most is choosing a larger filter than the minimum. A bigger filter means you clean it far less often, and it protects the system itself from damage that comes from running it too close to capacity. For example, on a thirty thousand litre pond we would not recommend a thirty thousand litre filter. We would suggest a larger one, or even two filters together. Otherwise you end up cleaning every week or so. A larger setup gives you a hassle-free system, though of course it depends on your budget. We always tell our customers: bigger is better for easier maintenance and longer filter life.
