Costs, Gear, and Time: Planning for Aquasoil vs Sand
When starting your aquascaping journey, one of the first big decisions is choosing between aquasoil and sand as your substrate. Each option shapes your planted aquarium differently—affecting everything from plant growth to maintenance routines and budget. This guide breaks down the costs, gear requirements, and time investment for aquasoil vs sand, helping you plan a thriving aquascape, no matter your experience level.
What’s the Difference? Aquasoil vs Sand in Aquascaping
Aquasoil is a nutrient-rich substrate, specially formulated to support aquatic plant health and encourage strong root systems. It’s typically made of natural soils, baked into small granules. Sand, on the other hand, is inert and doesn’t supply nutrients to plants on its own. Each medium offers distinct advantages and challenges for aquascapers.
Benefits of Aquasoil
- High nutrient content for lush plant growth
- Enhances water parameters for most aquatic plants
- Great for carpeting and rooted plants
Benefits of Sand
- Clean and minimalist appearance
- Safe for bottom-dwelling fish like corydoras
- Lower initial setup cost
Cost Breakdown: Aquasoil vs Sand
Initial Substrate Costs
| Substrate | Cost per 9L Bag | Coverage (per 20-gallon tank) |
|---|---|---|
| Aquasoil | $25 – $40 | 1-2 bags |
| Sand | $6 – $16 | 1-2 bags |
Aquasoil costs significantly more upfront. However, keep in mind you may not need to supplement with root tabs right away, as you would with sand.
Supplemental Costs
- Sand users often need to purchase plant fertilizers such as root tabs or liquid nutrients ($10 – $30 per year).
- Aquasoil users may not need extra nutrients for the first 6-12 months. After that, fertilization may be beneficial as nutrients deplete.
Other Potential Expenses
- Hardscape materials: Stones and driftwood look great with both, but are more visually impactful atop sand.
- CO2 Systems: While optional, CO2 injection is especially effective with aquasoil and demanding plants.
Essential Gear for Each Substrate
Gear for Aquasoil Tanks
- Fine mesh net or substrate leveling tool
- Quality water test kits for ammonia and pH
- Reliable filtration (find filters that prevent clogging)
- Strong aquarium lighting to match aquasoil’s growth potential
Gear for Sand-Only Tanks
- Sand flattener or rake for easy maintenance
- Turkey baster to clean debris off the surface
- Root tabs or a suitable fertilizer regimen
- Standard lighting, based on plant selection
Both setups require essentials like a heater, thermometer, and water conditioner. Want to explore the top starter tanks and gear? Check out our Beginner Aquascape Checklist.
Time Investment: Setup and Maintenance
Aquasoil Tanks: What to Expect
- Setup: Initial filling requires care, as aquasoil is dusty and can cloud the water if not handled gently. Plan for a 2 to 4-week cycling period as aquasoil leaches ammonia.
- Maintenance: Once stabilized, routine involves regular trimming, water changes, and occasional substrate topping up after 1-2 years.
Sand Tanks: What to Expect
- Setup: Simple and fast. Just rinse the sand well before use.
- Maintenance: Sand compacts over time. Stir the substrate occasionally to avoid anaerobic spots and clean debris with a siphon or turkey baster.
- Root-feeding plants will need ongoing fertilization, increasing time spent on routine care.
Which Substrate is Best for You?
If your main goal is lush plant growth and you’re willing to invest: Aquasoil is the top choice. It’s ideal for carpet plants and aquascaping competitions, but comes with higher cost and more careful setup.
If you’re aiming for a simple, inexpensive setup or have bottom-dwelling fish: Sand is excellent, especially if you incorporate hardy epiphytes or use root tabs for more demanding plants.
Many aquascapers combine both, using aquasoil in planted areas and sand in open sections for a balanced look and plant health.
Conclusion: Planning Your Ideal Planted Tank
Your substrate choice directly impacts your budget, equipment list, and ongoing maintenance routine. By weighing the costs, required gear, and time investment of aquasoil vs sand, you can design a planted tank that aligns with your aquascaping goals.
