My pond was pretty cheap AFTER setting it up. I know what I will do differently next time though. My favorite fish I kept was shubunkins (I can't spell) they were beautiful. My pond became over run with hyacith, letuce, and lillys. I think that is where they laid all of their eggs.
Maybe next time I go to tenessee, I will pick up some rock from a quary, and start a new pond. Still have all of my pumps and such.
