Checklist: Concave Layout Tutorial Setup Done Right

Looking to create a breathtaking concave aquascape layout? You’ve come to the right place! At Aquascaping Academy, we believe an organized, methodical approach delivers the best results. This step-by-step checklist ensures your concave layout setup is done right, guaranteeing a rewarding experience and a stunning focal point for any room.

What Is a Concave Aquascape Layout?

The concave layout is a popular aquascaping style where the hardscape and plants are arranged to dip in the center, creating a valley-like effect. This draws the viewer’s eye naturally into the tank and enhances depth, making even smaller aquariums feel expansive. This style suits both beginners and seasoned hobbyists, and it’s a favorite in aquascape layout styles competitions worldwide.

Benefits of a Concave Layout

Creates a natural sense of depth
Highlights hardscape materials and focal plants
Easy flow for fish and shrimp
Allows creative combinations of textures and plants

Concave Layout Setup Checklist

Here’s your comprehensive checklist to ensure your concave aquascape is beautiful and healthy from day one.

1. Gather Essential Materials

Tank: Clean, preferably rimless for best visuals
Lighting: Full-spectrum LED suited to plant needs
Filtration: Reliable filter (canister or HOB)
CO₂ System: (Optional, but enhances plant growth)
Substrate: Nutrient-rich aquasoil and fine sand
Hardscape: Rocks and driftwood offering contrast and structure
Plants: Foreground, midground, and background species
Water Conditioner & Bacteria Starter
Aquascaping Tools: Tweezers, scissors, and spatulas
Spray Bottle: For misting during setup

2. Plan Your Hardscape Layout

Sketch or visualize your desired valley shape with higher slopes at the sides and a lower center.
Position your largest rocks or driftwood on the sides to anchor the scape.
Use smaller stones and branches to blend transitions toward the center valley.
Secure hardscape with aquarium-safe glue if needed.

3. Add and Shape Your Substrate

Layer nutrient-rich aquasoil highest at the sides, sloping downward toward the center.
Cap exposed areas with fine sand in the valley for a natural path effect.
Use plastic dividers to prevent substrate mixing between zones.

4. Choose and Plant Compatible Flora

Foreground: Carpet plants like Hemianthus callitrichoides (Dwarf Baby Tears)
Midground: Bushier plants: Cryptocoryne or Staurogyne repens
Background/Sides: Tall varieties: Rotala, Vallisneria, or Hygrophila

Monitor water parameters daily during the initial cycle phase.
