- Vallisneria (Vallisneria spiralis)
- Water Wisteria (Hygrophila difformis)
Planting Tips And Tricks
Planting in substrate requires care and the right techniques. This helps your plants grow strong and healthy.
Use tweezers to place plants gently. Avoid burying the crown too deep to stop rot.
- Choose nutrient-rich substrate for better root growth
- Plant small roots first, then cover lightly with substrate
- Trim dead leaves to keep plants healthy
- Use root tabs if substrate lacks nutrients
- Avoid disturbing substrate after planting
Maintaining A Healthy Substrate
Aquascaping with planted substrate needs care to keep plants healthy. The substrate holds nutrients and supports roots well.
Good substrate care helps plants grow strong. It also keeps water clear and fish safe.
Preventing Compaction
Compaction happens when the substrate gets packed tightly. This blocks water and air from reaching roots.
To avoid compaction, gently stir the substrate now and then. Use tools or fish that dig to keep it loose.
- Stir substrate monthly with a soft tool
- Include burrowing fish or shrimp
- Avoid heavy decorations that press down
Managing Algae Growth
Algae can cover the substrate and plants. It competes for nutrients and makes the tank look dirty.
Keep algae in check by controlling light and nutrients. Clean excess algae by hand or with algae-eating creatures.
- Limit tank light to 6-8 hours daily
- Do not overfeed fish
- Add algae eaters like snails or shrimps
- Remove visible algae regularly
Regular Cleaning Practices
Cleaning the substrate keeps it healthy. Remove waste and debris to stop bad bacteria growth.
Use a gravel vacuum during water changes. Clean only part of the substrate to keep beneficial bacteria alive.
- Vacuum substrate every 2-3 weeks
- Clean 20-30% of the substrate at a time
- Check water parameters regularly
