Frequently Asked Questions:
Q1: Can I use tap water for my aquatic garden?

Q2: What aquatic plants are best for beginners?
A2: Java fern, Anubias, and water lettuce are hardy and easy to care for, making them great choices for beginners.
Q3: How often should I change the water?
A3: Change about 20% of the water every two weeks to maintain freshness, or as needed based on the health of the plants.
Q4: Can I add fish to my aquatic garden?
A4: Yes, small fish like bettas or guppies can be added, but it’s important to research their compatibility with the plants you choose.
Suggestions:
- Try themed aquatic gardens with seasonal decorations (e.g., beach, forest).
- Organize mini workshops with friends to share ideas and tips.
- Explore hydroponics with an emphasis on edible aquatic plants, such as watercress.
