Checklist: No CO2 Planted Tanks Setup Done Right
Designing a lush aquarium doesn’t require added CO2. Follow this expert no CO2 planted tank setup checklist and achieve healthy, beautiful aquascapes naturally.
Why Choose a No CO2 Planted Tank?
No CO2 planted aquariums are perfect for beginners and hobbyists seeking a low-maintenance, budget-friendly setup. Without pressurized CO2, your aquascape remains accessible and stable, with less risk of dramatic algae outbreaks or fish stress. Plus, slow-growing plants in low-tech setups often result in more manageable maintenance routines and a natural look that suits a variety of aquascape styles.
No CO2 Planted Tank Setup Checklist
Before diving in and adding water, ensure you have all the essentials for success. Use this practical aquascaping checklist to build a thriving, balanced aquarium from day one:
- Tank (Size Matters): A 10-20 gallon tank is ideal for easier stability. Larger tanks offer more flexibility in plant and fish choices.
- Lighting: Full-spectrum LED lights designed for planted tanks. Aim for 8-10 hours per day; avoid excess intensity to limit algae.
- Substrate: Choose a nutrient-rich substrate or supplement inert gravel/sand with root tabs for optimal plant growth.
- Filter: Gentle sponge or hang-on-back filter with adjustable flow. Ensure adequate water movement without disturbing delicate plants.
- Heater (if needed): Maintain stable tropical temperatures (22-26°C / 72-78°F), suitable for most popular aquatic plants and fish.
- Dechlorinator: Essential for removing chlorine and chloramine from tap water.
- Fertilizers: Use quality liquid fertilizers to supplement key nutrients. Root tabs benefit heavy root-feeders like cryptocoryne and swords.
- Aquascaping Hardscape: Rocks, driftwood, or other decor that won’t release toxins. Consider natural layout principles for visual balance. Read more about aquascaping hardscape ideas.
- Maintenance Tools: Plant tweezers, scissors, and a gravel vacuum for easy upkeep.
Best Plants for No CO2 Aquascapes
Certain aquatic plants thrive in low-tech aquariums without added CO2. Choose forgiving species that naturally adapt to your setup, such as:
- Anubias: Slow-growing and hardy, attach to wood or rocks.
- Java Fern (Microsorum pteropus): Tolerates shade and low light, easy to propagate.
- Crytocoryne (Crypts): Many species suitable; rooted in substrate, low light tolerant.
- Java Moss: Versatile, can be attached to hardscape or left as ground cover.
- Bucephalandra: Unique texture and color; thrives in low CO2 environments.
- Amazon Sword (Echinodorus): Will need root tabs, good for background planting.
- Vallisneria: Grass-like, ideal for adding movement and vertical height.

Step-by-Step: Setting Up Your No CO2 Planted Tank
- Plan Your Aquascape: Sketch a layout or gather inspiration photos. Consider focal points, negative space, and plant positioning for long-term harmony.
- Add Substrate: Layer your nutrient-rich substrate, sloping towards the back for depth. Place root tabs if using inert gravel or sand.
- Arrange Hardscape: Add rocks and driftwood securely. Leave space for plant growth and easy maintenance.
- Plant Selection & Planting: Arrange foreground, midground, and background plants. Use aquascaping tweezers for precise placement.
- Fill the Tank: Slowly add dechlorinated water to avoid disturbing your design.
- Install Equipment: Set up the filter, heater, and lighting according to manufacturer instructions.
- Cycle the Aquarium: Establish beneficial bacteria for a healthy ecosystem. Monitor ammonia, nitrite, and nitrate levels before adding livestock.
- Start Light Fertilization: Dose liquid fertilizer once per week and monitor plant response. Adjust as needed.
- Begin Regular Maintenance: Perform weekly water changes (20-30%), trim plants as needed, and clean filters. Learn more aquascaping maintenance tips.
Troubleshooting Common Issues
Algae Outbreaks
Maintain a consistent lighting schedule, avoid overfeeding, and ensure proper plant growth to outcompete algae. If issues persist, consider introducing algae-eating fish or shrimp (like Amano shrimp or Otocinclus catfish).
Yellowing or Melting Plants
Check for nutrient deficiencies. Consider increasing liquid fertilizers, adding root tabs, and double-checking plants’ specific requirements.
Cloudy Water
This is common with new setups. Ensure proper cycling, avoid overstocking, and perform regular water changes.
