Amanda and I put in a little water feature in our yard the other day. I wanted to do a full-fledged pond, but that would have required a lot of work and it would have also taken a lot of time and would have required taking out a lot of plants and greenery (not ok with Amanda). It is still very cool.

It is basically a 15 gallon tank at the bottom with smaller vessel above it. There is a pump that circulates the water and burbles. The water just trickles down the rocks right now. I may get a fountain statuary thing eventually, but that might take a while to find one I like.
Amanda also acquired many more plants for the front yard. She is unsure now about the color of the rocks as they don’t really match the rest of our 100 square foot yard, so we will probably replace them at some point.
After I cycle the water a few times, we will probably get a few plants and a couple of comets. They should be fine from the weather, but I dunno about wandering predatory felines.
