Last updated: May 2026
Quick summary
- What it is: Velvet-thin microbial turf hugging freshly unfurled leaves and driftwood ridges under six months tenure.
- Severity: 2 / 4 — Cosmetic / mild—signals immaturity more than doom
- Primary cause: Immature microbial competition plus CO2 learning curve artefacts.
- Primary fix: Hands-off observation with shrimp polish and stable lighting ramp—panic chemistry rarely warranted.
