Hi I have a pond about 5ft x 5ft and 3ft deep. 2 lilly`s,monkey flower,iris,creeping jenny,5 comets and tad poles.I wanted a rock waterfall but did not have the space so I used a flower pot instead.It has a 1200 gph pump in a filter box on the bottom and keeps the pond real clear.I had a pond at my old house so I learned by trial and error.It was fun learning from my mistakes.I just put a underwater light in and it looks great! I am building a skippy filter for it that I saw on here.This site has a lot of info and nice ponds,keep the info coming and Happy water gardening!!
