Skip high-tech pressure for the first tank. Use easy plants, moderate light, and patience so algae does not win.

Decide in 60 seconds
| Situation | Do now |
|---|---|
| Green water or glass algae explosion | Reduce light hours; check feeding and maintenance |
| Plants melting after move | Often normal for crypts; avoid uprooting repeatedly |
| Shrimp deaths after additives | Stop additives; large water change with conditioned water; reassess |
Why it matters
Beginners fail by copying high-tech scapes with low-tech budgets. Matching methods to tools prevents giving up on planted tanks.
Setup and tools
What good looks like
Plants show new leaves over weeks, algae is manageable with glass cleaning, livestock is stable.
What to notice
Step-by-step
Hardscape first
Wood and stone that leave space for flow and maintenance access.
Calm, well-managed pet
Plant choice
Start with epiphytes on wood and tough rooted plants.

6–7 hours on a timer. Increase only if plants respond cleanly.
Nutrients
Lean dosing; observe before adding more.
Livestock timing
Cycle fully before shrimp and fish.
When it is medical
Living context by region
Written for multi-region English readers. Prefer local vet advice and product labels where rules differ.
Common mistakes
- Max light day one
- Only stem plants that need CO2
- Skipping the cycle because "plants will handle it"
