I'm surprized no one has posted pics. yet. Many people use them and they are great. I used one as a temp. pond when I moved. My current home didn't have a pond. When I moved in, I placed a 300 gal on my patio to house my goldfish and Koi. I had a regular sump pump in the 300, piped to a 70 gal. stock tank. The 300 sat on the ground and the 70 was 8" higher sitting on cinder blocks. Plumbed the bung from the 70 out 6", 90 pointed up, a small section of pvc to another 90, then another section of pipe which lead to the 300. Very simple, unsightly, but effective and easy. I wish I would have taken pics. but had no idea about MFK back then.
