Due to limited access to the system during the summer months, we started off with feeder goldfish.

We added gravel to the bottom this week. The light color has been great at regulating the water temperature. It's also reduced the amount of waste just floating around in the water.

This picture also shows the 25 gal / hr water filter, the intake valve for the bottom row, and the outtake valve for the top row.

This project is funded by an agreement with the state of Tennessee.
