I've been begging my husband and sons for a pond for 35 years, I came home the other day to find a whole dug for my dream pond, my first questions is would I be better off starting off with a pond kits since I wasn't prepared for this surprise or am I better off buying everything on its own? I know I need a 20' x 32' liner but would like info on what pump or filter would be recomended for a rather small budget, I've been collecting rock for over 30 years so the landscaping will only take manual labor. Thank you.
