Procedure

1. Cut bottles according to diagram.

2. Using the Heated needle, poke about 4 holes in each bottle cap.

3. Fill each of the tiers with their respective materials ( the lowest with the pebbles, aquatic plant, water and fish. the middle with the material to be decomposed, worm and perhaps a spider included. In the uppermost tier, include the soil and grass seed)

4. Construct the eco column according to the diagram and include "doors" to open and feed your fish and to perform tests on the water. The string is used to pull the doors open.

5. Tape all of the peices together to ensure that water will not leak out and that fruit flies cannot get in. this will also make it much easier to carry, although I doubt you'd be taking it many places.

6. With the eco column completed, you need to feed the fish and every 2 days or so

7. Test the water for temperature, pH, DO, Turbidity, Nitrate and Ammonium levels about once a week.

8. After testing, add about the same amount of water that you took back into the ecosystem to water your plants and refill your aquarium. Pour the water into the opening at the top. It will reach your fish eventually.
