Pressurised pond filters and pump

What is a pressurised pond filter and pump

Pressurised pond filters are a ideal for small to medium size ponds, consisting of a canister which sits outside the pond and a pump within the water which pumps the water to it. From the filter canister the water is either returned direct to the pond or via a waterfall or other feature. The big advantage of pressure pond filters is that the actual filter canister can be buried so that very little is showing above the ground, making it much easier to hide than some other types of filter. Also the water is still under pressure when leaving the filter so you have a bit more flexibility when deciding where to possition the filter. i.e. does not have to be above the water line of your pond.
