18.5. Heavy Stocked Maintenance
Heavy Stocked Maintenance: ONLY if one has very heavily stocked aquarium with only moderate amounts of biofiltration one should read on. This analysis is very long and boring.

There are a host of YouTube videos emphasizing that it is essential to “deep clean” and “deep vacuum” the substrate of an aquarium at least once a week. We do NOT recommend doing this.
