I have always had issues with this and can't seem to wrap my brain around setting up pond filters/ fountains, ect. all that stuff is like algebra to me
I am not understanding how the water gets from the pond TO the filter. So if I set a filter box outside of my pond and then what? I have a pump, so the pump pumps water from the pond into the box where it is forced through a layer of foam, ect to clean it and then it is spilled back out. ?
I think this is not right because how does the pump pump dirty water BEFORE it is sent through the filter? Doesn't it clog up the filter? Don't I want only clean water running through the filter?
I know my question is dumb
Please help!
