What is the point of my Pond filter?
I have 2 pumps in my pond. One pump is for creating the waterfall. The other pump pumps water up a pipe into a large black box and from this black box the water returns back into the pond (through a different pipe). Inside this box there is a long horizontal pipe stretching the length of the box near the ceiliing. When the pump runs it is this ceiling pipe that sprays water into the box. There is another pipe sticking out from the floor of the box about 4-5 inches up (but below the other pipe near the ceiling). On the floor of this box is some kind of spungy material (2 sheets of it). When i watch this "filter" box in action the water, as i mentioned already, comes in (from the pump) to the box via the ceiling pipe (this pipe has little holes in it so it sprays in the box like a sprinkler). And once the box fills with water and reaches the portruding pipe (at 5 inches from the floor) then it drains back into the pond.
Now tell me, what is the purpose of this.
I just dont see how this filter box is actually filtering out things since my pump has a small filter thingy attached underneath where it strains out the water before going in to the box thus preventing large chunks from getting into the filter box. And even when water enters this box nothing actually happens to it..
