Hi Humbirdlover, Welcome to the forum!!! It is nothing fancy. it bought it from Menards a few years ago. It has both a mechanical filter which consists of three o rings, a bunch of bio-balls, and a uv light. I think all three components are necessary for good filtration. I also have a second pump just to have a little more water flow on the waterfall. I think it's important to have a lot of water moving to provide O2. I am actually thinking of redoing the waterfall and making it longer. I'll have to build some sort of frame to put the rocks on so I can still get to the filter. I recently bought a old milk can and put vines in it. It helps hide the filter too. Thanks for the compliment. I was a rank beginner 4 years ago and probably made every possible mistake when I started, but the last few years I have learned a lot on the gpf and it has helped! btw, we are going to charlottesville va this weekend to meet our daughter and her boyfriend. Know any good places there?
CE, The raccoons come by the pond almost every night! I have learned to deal with it, but I can't stand the skunks we have had lately. My neighbor filled a hole they were making into a nest. Hopefully they stay away now.
