Maintenance & BBA Experiment Prep

🧰

March 22, 2026

Performed the weekly maintenance water change.
Completed a large water change, draining approximately 90%+ of the sump and ~70–75% of the display. This session included additional cleanup and preparation for a new algae-control experiment.
Maintenance performed:
- Replaced intake netting due to heavy buildup of black beard algae (BBA)
- Rinsed pre-pump sponge to remove debris and restore flow
- Light system cleanup to reduce accumulated organic matter
Dosed Prime during refill and added Stability due to media disturbance and net replacement.
Preparing to begin a new 24-hour “Aquarius” treatment experiment targeting remaining BBA. This will be monitored closely to evaluate effectiveness and plant safety.
System remains stable heading into the experimental phase.
