Our Store has displays that we change every few years. Come on in, see our fish on display, some of which are 21 years old, and have some fun! We have a boulder fountain display, formal waterfall display, pondless waterfall display, landscape display, and a koi pond display. We offer personalized help in our store for your project by folks who have worked and continue to work in the field. If you’re a do-it-yourself person, you’ll get help from someone who builds, maintains, and services ponds, waterfalls, and water features on a regular basis.
