Hello, I was hired by a relative to renovate their pond and landscaping. The landscaping is the easy part; however, this is my first pond project. The pond is already dug, was first installed about 12 years ago (was neglected and became overgrown). I have removed everything, plants, liner, etc. Everything looks good, but now I need to start ordering equipment, liner, etc. The pond is 10'x13' and 2' deep. I will need a liner about 15'x20' according to http://watergarden.com/pages/build_wg.html. Has anyone ordered from them before? Anyway's, another relative gave me an Aqua Ultraviolet Ultima II 4000 Filter and Sunami pump. Will this filter and pump work for this pond or is it overkill? Should I buy another filter or pump? I would need help with the plumbing, the pump inlet and outlet are 2" or 3" and the filter inlet and outlet are 1.5". Do I use flexible tubing? What size? Any advice or suggestions would be greatly appreciated. Thanks, Nolan
