Post-Incident Stabilization Water Change

⚠️

February 16, 2026

Performed a follow-up stabilization water change.
- Sump: Drained as much as possible
- Display: ~50–60% drain (experimenting with smaller display changes)
- Prime was properly dosed prior to refill
Last week included two water changes:
1. The initial large change where Prime was accidentally omitted.
2. A midweek corrective water change (Wednesday) to support recovery.
Current livestock status:
- Remaining Cherry Barbs
- Betta
- Kuhli Loaches (when visible)
- Shrimp and snails
The visual density of the tank is noticeably reduced due to recent losses, but the system appears stable. No new signs of distress observed.
Moving forward, experimenting with slightly smaller display water changes while maintaining heavy sump turnover.
System focus: stability, bacterial support, and slow recovery.
