Thanks to super wal-mart I found everything I needed to make a carbon/bio filter using a 2gallon water bottle with pour spout, carbon rocks filter matter(very course)and woven filter fiber material. Oh, plastic tubing with a pump.It is working!!!!!!!!!!

The water is coming out of spout, it works same function as a waterfall. See my pond is small and were I leave it is hard to get what cha need.
