Thanks Lee! I am in NJ where winter is a factor. I am building this pond
myself. And thanks to all you pond enthusiasts out there who have passed on
your fast knowledge. You are all just the best! By the way, I kept large
goldfish for 10 years in a 100 gallon pond outside (winter and everything) only
18" deep at its lowest point, and they lived through it all. Those Koi must be
the premadonnas of the fish world! Thanks again, I appreciate the help!
