My friend is a feng shui fanatic. To balance chi, she wanted a garden pond with a pressured pond filter. Busy as she is with her restaurant, I was called to get the information she needed inclusive of costs. I found a site that gave all the data my friend needed which included the pressurized pond filter to keep the water clean, clear and beautiful. In a matter of days, the fish pondwas complete with lotus flowers and so lovely to look at.
