What You Need
Fish tank (20-50 gallons)
Grow bed for plants
Water and air pumps
Grow medium (clay pebbles or gravel)
PVC pipes/tubing
Fish (tilapia, goldfish, catfish)
Plants (lettuce, herbs, tomatoes)
pH test kit (optional)
Light source
Steps
1. Set Up the Fish Tank: Choose a location with electricity and light. Fill the tank with dechlorinated water and set up a pump to circulate water between the tank and grow bed.
2. Build the Grow Bed: Place the grow bed above the tank. Fill with grow medium and use PVC pipes to channel water from the tank to the bed and back.
3. Add Fish and Plants: Introduce hardy fish like tilapia or goldfish. Add plants that thrive in water, like lettuce or herbs.
4. Monitor Water Quality: Regularly test pH (6.8-7.2) and check ammonia, nitrate, and nitrite levels. Adjust as needed with buffers or partial water changes.
5. Maintain the System: Feed fish daily, remove uneaten food, check pumps, and keep water clean. Remove dead plants or fish immediately.
Tips for Success
Start Small: Learn with a small system first.
Choose Compatible Species: Match plants and fish with similar needs.
