Purchased liner, pump, filter, electrical, plants and landscaping rock for our river and pond project. The pond was 6 ft deep and about 12x16 so we needed a large liner - no problem. Didn't have to weld seams or worry about holes.
The pump works around the clock and we clean the filter about once a week which provides great composting material. Stays clean and with treatment fairly clear.
Probably the best pond place around Parksville and QB.
