I actually found direction for raising the catfish in a swimming pool online at E-How. It seems pretty simple to do. We have a wholelot of trees in the yard, so finding a shady place for the pool should not be a hard thing to do.
On the side of the house (north) that is the very shadiest, we have an outside electrical outlet; so that would also be the best place to be able to plug in the pump and filter.
The directions say that you should drain out about 1/3 of the water from the bottom of the pond every week, and that should be wonderful to use watering my cucumbers and tomatoes as well. I would not have to set up the whole hydroponics plan if I just followed these instructions and then drain the extra water with a hose out onto where I want to water.
