old son build his own small above ground pond, with my help of course. I am thinking of using like maybe an old shop sink, a old hand wash tub, maybe one of those ice cream freezers at the store with the sliding doors on top. Something that is like stand up height and can be up on the main patio out of the weather since it will be pretty small. My concern is how well would it do if it is always under a roof where it wouldn't get any direct sunlight? Maybe I can put it on the end where it would get some late afternoon sun. I need him to start learning some responsibility and he sure does like watching the fish in my pond.
