You can see the water splashing up in the little fountain feature. I have a pump and combo Bio filter and UV filter which the water gets drawn thru when it comes up the fountain feature. Thats what keeps pond water clean and healthy. I do love that pond. I know it is not very big but I looked for two years for just the right "big" pond for my yard. I had my two small 35 gallon ponds which have no filters or splashers. I just drag out the hose and add more water from the bottom every few weeks. But this one while small from ponders point of view is what fit into my yard. If I had lots of room I would have a much bigger pond but you have to work with what you have.
