We occasionally have in stock various filters, pumps and etc. from folks who have decided to enlarge their pond (some not for the first time – so the advise here would be to make your pond as large and as deep as possible the first time). Since this list changes weekly, it would be best to contact us on availability and savings of our previously owned equipment. It will include vortex filters, slide valves, pumps, ultraviolet lights, skimmers, and bio-falls. All of the above is completely re-conditioned.
