We sealed the wood, and put flagstone around it. We still need to adjust the pump a bit to get the right about of water bubbling up, but I love it. The sound of the water is so nice!
Just a few weeks ago we were in the cities for the weekend, and we drove back to our old neighborhood to take a look around. As we were leaving the area, we noticed that there was a pond liner out on someone's driveway with a sign that said "Free." Craig looked at me and said, "Should we?" So we did. We brought that liner home, and have been working on installing it and landscaping around it. I have lots of inspiration pictures on pinterest, as well as information from friends about taking care of a pond so I have an idea of how I want it to look eventually.
The next step is to get an aerator or fountain for it, as well as some water plants and chemicals to keep the water clean. Then we will fill it with water, turn on the pump and begin to enjoy it.
