Observations

Maintenance is intentionally limited. The only routine tasks are cleaning the glass roughly once per week and feeding the tank daily. No frequent testing, no chasing numbers, and no constant adjustments.

Green Star Polyps dominate the system and act as a natural form of nutrient export. This tank has remained stable and continuously running for over a decade, proving that simplicity and consistency can be just as effective as high-maintenance approaches.
