To maintain the health of fishes, experts propose the following methods:

1. Maintain a pH level from six to eight.
2. Sustain oxygen in the tank, as it is necessary for fish to survive. Be prepared with a battery-based aerator should power outages occur.
3. Set up the system away from direct sunlight.

The selection of plants offers a wide variety to choose from like vegetables, herbs, fruits, and flowers. Plants like the system because there is no weed competition and they do not have to search for food or water. Among the popular choices for plants are lettuce, tomatoes, strawberries, cucumbers, and watercress.
