What is a Dutch Style Aquarium?

A Dutch Style Aquarium is a high-density planted tank focused on vibrant aquatic plant arrangements, often featuring over 10–15 species, each selected for unique color, height, and texture. The design follows strict aquascaping rules emphasizing contrast, order, and rhythm — avoiding hardscape elements like wood or rock. Instead, the plants themselves form the layout’s architecture.

Origins in the Netherlands and the NBAT Tradition

This aquascaping style was formalized by the Nederlandse Bond Aqua Terra (NBAT) in the early 20th century. To this day, many aquascaping contests in Europe — including NBAT competitions — follow specific Dutch layout rules, such as the “20-foot view” test, which evaluates visual impact from a distance.

Key Visual Characteristics

• Multiple plant “streets” arranged diagonally or vertically
• Bold color contrasts: green vs. red, narrow vs. broad leaves
• Clear zones of height: low carpets, mid-level fillers, and background curtains
• No hardscape distractions — no rocks, driftwood, or decorative elements

Dutch vs. Nature Aquarium Style

Core Principles of Dutch Aquascaping

Designing a Dutch tank is like composing a classical painting — every stroke is deliberate.

Contrasts in Color, Texture, and Height

A Dutch tank should feel dynamic and full of visual energy. You achieve this by carefully balancing:

• Bold color pairings – like rich red Ludwigia sp. next to vibrant green Limnophila or flowing Vallisneria

• Contrasting leaf shapes – such as round, compact Cryptocoryne beside fine, spiky Rotala

• Height variation – using short groundcovers, medium bushy plants, and tall background species

This deliberate contrast brings clarity, movement, and character to the layout. Without it, even healthy plants can look monotonous. Aim to keep each plant group visually distinct, so the tank feels harmonious but never flat.

Layered Plant “Streets” and Depth Creation

Plant “streets” are linear groupings of the same species, carefully arranged to create rhythm and structure within the tank. These streets:

• Run from front to back or diagonally across the tank
• Use 5–10 stems per group
• Are slightly offset to guide the viewer’s eye and build visual depth

In classic Dutch layouts, these groupings form horizontal terraces of different plant heights, typically broken down into 8–10 distinct plant zones:

• Foreground: Up to 10 cm – carpeting plants and low rosettes
• Midground: 15–20 cm – bushy, medium-height species
• Background: 25–40+ cm – tall stem plants and curtain species

This layered structure enhances the contrast introduced earlier by giving each group its own space and vertical tier. By positioning each group with clear boundaries and consistent height within its zone, the aquascape gains both visual rhythm and a strong sense of depth.

💡 Tip: Avoid mixing plant types or sizes within a single street. Uniformity within the group and contrast between adjacent streets is key to creating a cohesive Dutch look.

Focal Points and the “Golden Ratio”

One or two focal points should dominate the viewer’s attention. These are often:

• Tall red plants
• Bushy species like Pogostemon erectus
• Placed using the Golden Ratio (1:1.6) for aesthetic harmony

Avoiding Symmetry and Visual Clutter

Symmetry is discouraged in Dutch aquascaping. Instead:

• Use asymmetry to build movement
• Space out groups with open swim zones
• Avoid mixing species in the same cluster

Equipment Essentials for a Dutch Aquascape

Setting up a Dutch Style Aquarium goes beyond planting beautiful stems. It requires the right tools to support dense growth and vivid coloration. Here’s what your tank needs to thrive.

Tank Size, Dimensions, and Layout Planning

While Dutch aquascapes can be created in almost any size, larger tanks (80–200 liters or more) provide better depth and layout possibilities.

Ideal dimensions:

• Width: at least 40 cm for plant layering
• Length: 90 cm+ for multiple plant groupings
• Height: 40–50 cm for vertical contrast

💡 Tip: Use black or frosted backgrounds to highlight plant colors and keep attention on the layout.

Lighting Systems for Lush Plant Growth

Lighting intensity and spectrum have a dramatic effect on plant health.

• Full-spectrum LED lights (6500K–8000K)
• ~30–50 lumens per liter
• 8–10 hours per day with a timer

Avoid “cheap white LEDs” — they lack the full PAR range needed for red plant development.

CO₂ Injection Systems and Techniques

CO₂ is not optional in a serious Dutch setup. It enhances:

• Growth rate
• Red coloration
• Resistance to algae

Setup essentials:

• CO₂ regulator with solenoid
• Inline or in-tank diffuser
• Drop checker for 30 ppm CO₂ range

⏱️ Automate injection with your light schedule for consistency.

Filtration and Circulation Best Practices

Clear water and low organics help plants absorb nutrients efficiently.

Filtration:

• Canister filter with adjustable flow
• Fine sponge + bio media
• Flow rate: ~5–10x tank volume/hour

Circulation:

• Gentle flow to prevent CO₂ pockets
• Avoid surface agitation (minimizes gas loss)

Substrate & Fertilization Strategies

The foundation of any Dutch tank is — literally — the substrate.

Nutrient-Rich Base Layers and Additives

Use active soil substrates designed for planted tanks.

Popular options:

• ADA Amazonia
• Tropica Aquarium Soil
• JBL ProScape VolcanoMineral + soil cap

You may also layer with:

• Laterite or root zone enrichers
• Mineralized topsoil with sand cap (advanced)

Root Tabs vs. Water Column Dosing

Some root-heavy species (Cryptocoryne, Echinodorus) need localized nutrients.

• Insert root tabs near base of large root systems
• Replace every 1–2 months

Water column fertilization supports stem plants and fast growers.

Weekly Fertilization Schedule for Dutch-Style Success

Follow the Estimative Index (EI) or ADA lean dosing method:

💧 Monitor nitrate, phosphate, and iron levels to fine-tune your dosing.

Dutch Style Aquarium Layout: Step-by-Step

Creating a true Dutch aquascape requires both vision and precision. Here’s a layout workflow used by experienced aquascapers:

Step 1: Plan Your Plant Zones

Divide the tank into foreground, midground, and background zones.

• Foreground: carpeting plants or low groundcovers
• Midground: compact stems or bushy varieties
• Background: tall curtain plants or red focal species

Use sketches or digital planners (e.g. Tropica Layout Tool) to visualize zones.

Step 2: Choose 10+ Contrasting Species

A proper Dutch tank includes 10–20 plant species with:

• Leaf contrast: broad vs. needle-like
• Color variation: greens, reds, pinks
• Growth types: rosettes, stems, runners

Example contrast combo:
Ludwigia repens (red stems) next to Limnophila sessiliflora (fine green filaments)

Step 3: Create Plant “Streets” and Rhythm

Plant “streets” in rows from front to back, forming visual corridors. Each street:

• Has 5–10 stems
• Ends at a focal point or leads the eye diagonally
• Is slightly offset from neighboring streets

Do not overcrowd — leave negative space for rhythm and clarity.

Step 4: Planting and Anchoring Techniques

Use aquascaping tweezers for precise placement.

Tips:

• Angle stem plants for better rooting
• Anchor floaters or runners with plant weights
• Use planting grids if working with loose soil

Finish by misting everything before slowly filling the tank to avoid plant disturbance.

Best Plants for a Dutch Style Aquarium

Dutch aquascapes are celebrated for their plant diversity. A successful layout typically features 10 to 20 carefully chosen species that differ in shape, color, and height.

Foreground & Carpeting Plants

Use compact or creeping species to cover the front area and soften transitions.

• Helanthium tenellum ‚Green‘ – Delicate grass-like carpet
• Cryptocoryne parva – Slow-growing with small leaves
• Blyxa japonica – Bushy and vibrant, adds motion in current

Midground Accents

These plants serve as “volume builders” in the central zone.

• Pogostemon helferi – Unique curly leaves for texture
• Lobelia cardinalis mini – Bright green with round leaves
• Staurogyne repens – Dense and bushy growth

Background Curtain Plants

Tall and fast-growing, these species form visual backdrops.

• Limnophila sessiliflora – Fast-growing, feathery green stems
• Myriophyllum mattogrossense – Adds a soft, flowing texture
• Vallisneria spiralis – Ideal for curtain effects

Red and Contrast Plants for Focal Points

Bold red or pink plants create powerful focal points and contrast.

• Ludwigia sp. Red – Deep red hues, thrives under strong light
• Alternanthera reineckii ‘mini’ – Compact, vivid purple-red
• Rotala wallichii – Delicate needle leaves with pink accents
• Ludwigia pantanal – Intense coloration, high maintenance

Lighting, CO₂, and Water Parameters

Plant health and coloration in a Dutch style aquarium depend on a stable and well-tuned environment.

Spectrum and Intensity for Dense Growth

Dutch tanks demand strong, full-spectrum lighting to support lush growth and vivid reds.

Recommended lighting:

• LED (6500K–8000K)
• 0.5–1 watt per liter (for LED)
• PAR at substrate: 50–80 µmol/m²/s

📌 Red plants (e.g., Rotala, Ludwigia) need high light to maintain color.

Maintaining Consistent CO₂ Levels

CO₂ must remain stable throughout the lighting period.

• Aim for ~30 ppm CO₂
• Inject 1–2 hours before lights on
• Turn off CO₂ 1 hour before lights off
• Monitor with a drop checker or CO₂ meter

Warning: Fluctuating CO₂ is the #1 cause of algae in high-tech tanks.

Target Water Parameters

Use a quality test kit to monitor these parameters.

These are the perfect conditions for most of the plants, but please take your fish’s preferred temperature range into account when adjusting the water.

Maintenance & Trimming Techniques

A Dutch aquascape is a living sculpture — without regular care, it will quickly lose its structure.

Weekly Pruning and Shaping Routines

• Trim fast growers like Rotala and Limnophila weekly
• Use aquascaping scissors to shape bushes and streets
• Replant healthy tops, discard lower stems
• Maintain visible separation between plant groups

Managing Plant Overgrowth

Prevent “plant soup” by:

• Trim fast growers like Rotala and Limnophila weekly
• Use aquascaping scissors to shape bushes and streets
• Replant healthy tops, discard lower stems

Algae Prevention and Troubleshooting Tips

Even the best setups face algae. Here’s how to keep it at bay:

Tips:

• Keep CO₂ and lighting consistent
• Perform 40–50% water changes weekly
• Use Amano shrimp, Otocinclus, or Nerite snails for natural cleaning
• Don’t overfeed fish — excess organics fuel algae

Dutch Aquascaping for Competitions

Dutch aquascaping is not only an art but also a competitive discipline, especially in Europe.

NBAT Rules and the “20-Foot Squint Test”

The Nederlandse Bond Aqua Terra (NBAT) established strict judging criteria:

• The “20-foot view”: The layout must impress even from a distance
• Plants should be healthy, distinct, and well-contrasted
• Open spaces between groups are mandatory
• Overuse of a single color or height lowers the score

Judging Criteria in Competitions

NBAT and other Dutch-style contests evaluate:

• Plant health & vitality
• Contrast and composition
• Color harmony
• Layout logic and flow
• Absence of algae or clutter
• Balanced fish stock

💡 Tip: Judges prefer tanks with strong visual flow, not just color bombs.

Presentation Tips

• Clean glass, no visible equipment
• Use spotlights or rimless tanks for maximum clarity
• Photograph from the frontal “judging” angle only
• Time your trim 5–7 days before submission for perfect shape

Compatible Fish and Invertebrates

Fish are welcome in Dutch tanks — but they must support the aesthetic.

Best Fish Species for Plant Safety

Choose peaceful, plant-safe species that stay small and school tightly:

• Rummy-nose tetras (Hemigrammus rhodostomus)
• Cardinal tetras (Paracheirodon axelrodi)
• Harlequin rasboras (Trigonostigma heteromorpha)
• Small pencilfish, dwarf corydoras, or ember tetras

Avoid:

• Cichlids
• Goldfish
• Digging or uprooting bottom dwellers

Clean-Up Crew: Shrimp and Snails

A good maintenance crew can help prevent algae:

• Amano shrimp – Great for filament algae
• Nerite snails – Excellent glass cleaners
• Otocinclus catfish – Gentle on plants and effective on biofilm

Common Mistakes and How to Avoid Them

Even experienced aquascapers fall into these traps:

Troubleshooting Common Dutch Aquascaping Issues

Even the most carefully planned Dutch aquascapes can face setbacks. Whether it’s fading colors, melting stems, or uncontrolled algae, recognizing and resolving these issues early will help you maintain a healthy and visually stunning layout.

Pale or Yellowing Leaves

Cause:
Nutrient deficiencies — usually nitrogen, iron, or magnesium.

Solution:

• Check your fertilization routine, especially macros (NO₃, PO₄, K⁺)
• Add a chelated iron supplement if new growth looks yellow
• Ensure CO₂ and lighting are not fluctuating — inconsistency can block nutrient uptake

Leggy or Spindly Growth

Cause:
Insufficient light intensity or poor spectrum

Solution:

• Upgrade to higher PAR LED lighting (~50–80 µmol/m²/s at substrate)
• Reduce shade from neighboring plants with proper pruning
• Check that red plants receive direct light and not diffused shadows

Algae Overgrowth

Common types:

• Green spot algae – often caused by low phosphate
• Hair algae – triggered by unstable CO₂ or excess organics
• Black beard algae (BBA) – thrives under fluctuating light/CO₂

Solution:

• Maintain 30 ppm CO₂ with consistent injection start/stop times
• Dose phosphate (~1–2 ppm) weekly
• Increase water changes (50% weekly), reduce feeding
• Use Amano shrimp or spot-treat stubborn patches with Seachem Excel

Red Plants Turning Green

Cause:
Light or CO₂ is too weak to trigger anthocyanin production

Solution:

• Increase light intensity and duration (up to 10 hours max)
• Ensure CO₂ is stable and saturating at lights-on
• Use complete micronutrients and dose iron-rich fertilizers regularly
• Don’t crowd red plants — they need unobstructed vertical light

Melting Cryptocoryne or Vallisneria

Cause:
Sudden environmental changes (substrate swap, CO₂ start, temperature shifts)

Solution:

• Be patient — these species regrow from root systems
• Avoid disturbing root zones after initial planting
• Maintain stable parameters (no big swings in pH, temp, KH)

Key Takeaways

• A Dutch Style Aquarium emphasizes plant arrangement, not hardscape
• Use layered plant “streets” with varied color and texture
• Maintain strong lighting and CO₂ injection for best growth
• Choose 10–20 plant species with contrasting traits
• Avoid symmetry, clutter, and mixed plant groupings
• Prune regularly and maintain consistent parameters
• Participate in NBAT-style contests to showcase your layout
