This it the beginning of our indoor system we are experimenting with. We traded a guy an old sewing machine we were not using for the fish tank, the tubs were purchased at good will for $0.99 and on have off day so $0.50 each. Holes were drilled into the bottom and filled with the unwanted lava rock from our yard. The people who owned our house before us must have owned stock in rock and stone company. We let it run for a few days, then added fish. We will be adding some grow lights tonight. The grow lights were purchased at Menards for $20 for the fixture and another $20 for the bulbs. Fist time attempting this indoors so will keep you posted. If it goes well will switch over to Tilapia.
Why goldfish? We can buy 100 feeder fish at our pet store for $12.95. is not bad if something goes wrong. Plus they grow bigger and will eat algae, duckweed, and other scraps put into the tank. They are relatively hardy and will take abuse while we work bugs out of the systems.
