does something like that allow you to make water features in a foam background lets say? Im trying to understand how people make waterfalls or the like. Is there a filter for the water and also a seperate pump to push the water up the pipes to the waterfall? I need to make some sort of water feature in my newest vive but im not sure how most people do it, I dont really want a huge waterfall, just some sort of bubbling stream into a shallow pool of some sort. any ideas?
