Goldfish Tank Maintenance: Air Stone and Filter Schedule

Stephanie asks about air stone duration and filter cleaning frequency. Robyn recommends:

• Run air stone continuously.
• Weekly 50% water changes (more if tank small/overcrowded).
• Rinse mechanical filter media weekly; replace chemical media every 2 weeks.
• Preserve biological filter media (don't over-clean).

Tank size and fish size determine exact schedule.
