Calculating Amount: Formula: (Length × Width × Depth) ÷ 60 = pounds needed Example: 40-gallon breeder (36” × 18”), average 2.5” depth: (36 × 18 × 2.5) ÷ 60 = 27 lbs

Phase 2: Hardscape Layout (Day 8-10)

The Golden Rule of Aquascaping

Use the Golden Ratio (1:1.618):

Divide tank visually into thirds
Place focal points at intersection points
Never center main elements
Create flow and movement

Hardscape Placement Techniques

Iwagumi Layout:

Oyaishi (main stone): Largest, at focal point
Fukuseki (secondary): Medium size, supports main
Soeishi (tertiary): Small, grouping
Suteishi (smallest): Accent stones

Nature Style:

Place largest hardscape first
Create triangular composition
Group elements (don’t spread evenly)
Leave open foreground
Consider viewing angles

Dutch Terracing:

Plan plant groupings
Minimal hardscape
Think in layers
Color progression

Testing the Layout

Before Adding Water:

Photograph from multiple angles
View from seated eye level (how you’ll usually see it)
Check proportions (hardscape shouldn’t overwhelm)
Ensure stability (stones must be secure)
Plan plant placement mentally

Tips:

Step back frequently
Look from across the room
Take breaks and return with fresh eyes
Don’t rush this step

Phase 3: Substrate Installation (Day 11)

Substrate Layering

For High-Tech/Active Substrates:

Layer 1 - Base (0.5 inch):

Optional: Laterite or nutrient-rich base
Provides iron and minerals
Not essential but beneficial

Layer 2 - Active (1.5-2 inches):

Aquasoil (ADA Amazonia, Fluval Stratum)
Main nutrient source
Pack gently

Layer 3 - Cap (0.5-1 inch):

Sand or fine gravel
Visual appeal
Protects aquasoil
Easier planting

For Low-Tech/Inert Substrates:

Single Layer (1.5-2 inches):

Gravel or sand
Add root tabs (Seachem Flourish Tabs)
Create slopes
Simpler installation

Creating Contours

Sloping Technique:

Highest point: Usually back corner
Lowest point: Front center
Gradual slope: No obvious cliffs
Natural look: Mimic river banks

Building Up Areas:

Use lava rock under substrate to build height
Creates caves for fish
Saves substrate
Prevents anaerobic pockets

Phase 4: Planting (Day 12-14)

Plant Preparation

Unpacking Plants:

Remove from packaging
Separate from rock wool or substrate
Rinse roots gently
Trim damaged leaves
Identify planting location

Pre-soaking:

Optional: Dip in bleach solution (1:20) for 2 minutes
Kills algae and pests
Rinse thoroughly
Dechlorinate before planting

Planting Order

Start from Back to Front:

1. Background Plants:

Stem plants (cuttings)
Tall Cryptocoryne
Vallisneria, Sagittaria
Plant deep, remove lower leaves

2. Midground:

Cryptocoryne
Anubias (attach to wood/rock, don’t bury rhizome)
Java Fern (attach, don’t bury)
Medium stem plants

3. Foreground:

Carpeting plants (small plugs, spaced appropriately)
Small Cryptocoryne
Monte Carlo, HC Cuba, Dwarf Hairgrass
Plant densely for faster fill-in

4. Mosses:

Attach to wood/rock with thread, glue, or mesh
Can also let float initially
Attach last (don’t disturb other plants)

Planting Techniques

Stem Plants:

Cut bottom 2-3 inches at 45-degree angle
Remove lower leaves (prevent rot)
Plant 1-2 inches deep
Group 3-5 stems together
Space according to mature size

Rosette Plants (Crypts, Swords):

Plant entire root ball
Don’t bury crown (where leaves meet roots)
Can split large plants
Expect “Crypt melt” (normal stress response)

Carpeting Plants:

Separate into small plugs (1-2 inches)
Plant 1-2 inches apart
Use tweezers for precision
Plantings will fill gaps
Can use dry start method for faster establishment

Rhizome Plants (Anubias, Java Fern, Bucephalandra):

Critical: Never bury the rhizome (horizontal stem)
Attach to hardscape with:
- Cotton thread (dissolves)
- Super glue gel (cyanoacrylate, aquarium-safe)
- Fishing line
- Plant ties
Roots can be in substrate, rhizome must be exposed

Plant Selection by Tank Type

Remove plate when done

Water Source:

Tap water: Use conditioner to remove chlorine/chloramine
RO/DI: Remineralize before use
Temperature: Match room temp to prevent condensation

Aquasoil Ammonia Management

If Using Active Substrates (ADA Amazonia, etc.):

Expect:

Ammonia release for 1-4 weeks
This is NORMAL and necessary
Heavily plant to absorb ammonia
Do NOT add fish yet

Protocol:

Plant heavily immediately (plants use the ammonia)
Test ammonia every 2-3 days
Do water changes if ammonia >2 ppm
50% water changes every 2-3 days for first 2 weeks
Cycle completes when ammonia = 0, nitrites = 0

Fishless Cycling with Plants

Advantages:

Plants provide immediate biological filtration
Reduces cycling time
Immediate aquascape appearance
Less stressful than fish-in cycling

Process:

Week 1-2: Heavy water changes (manage aquasoil ammonia)
Week 3-4: Test parameters every few days
Week 4-6: Parameters should stabilize
Add fish gradually: 3-5 at a time

Monitoring:

Ammonia: Should be 0 before adding fish
Nitrite: Should be 0 before adding fish
Nitrate: Will accumulate (good sign)
pH: Monitor (active substrates lower pH)

Phase 7: Initial Maintenance (Weeks 2-8)

Water Change Schedule

High-Tech (First Month):

Daily first week: 25-30% (if using aquasoil)
Every other day week 2: 25-30%
