Guppy Riparium Patio Pond (No Filter Low Tech)

I've been thinking about adding a new patio pond to the lineup for a while now. The other ones were cool, but I recently dismantled them to make space in the animal room. I wanted to make this simpler though.

I personally think it's a great no filter low tech solution that's really easy to make. What do you think?
