3. Trim & maintenance schedule
A layout that peaks once and declines wasn't maintained — it was assembled. Weekly maintenance is what separates a photo-op from an aquascape that matures.
- Weekly: water change (30–50%), glass cleaning, dose ferts per your plant load.
- Every 1–2 weeks: trim stem plants back to just above the previous trim line — never let them reach the surface and flop.
- As needed: thin carpet plants that are overgrowing their intended footprint; remove any melting or decaying leaves immediately, they foul water fast.
- Monthly: check CO2 diffuser output and clean if bubble rate has dropped — a common silent cause of stalled growth.
