Couldn't find this exact pond DIY instructions but it should be pretty clear from the photo sequence. Large tractor tire trimmed, prepare earth, plastic lining, fill with water, secure around tire, fill in earth around place stones, insert filtered pump fountain from local hardware store, add landscape as needed. Enjoy.
This advice is intended for anyone installing a small (under 1000 gallons - about the size of 10-person hot tub or less) prefab garden pond or other little container pond on a patio or balcony. I've had several different types of ponds over the years, and, after a few learning curves, I've got a system I really like—easy to care for with healthy water, plants, and fish.
