Stability over shortcuts

Coral growth is mostly a stability problem, not a magic-product problem. This playbook gives practical systems for flow, light, feeding, and maintenance.

Module 1: Build repeatable control loops

Use weekly trend reviews instead of reacting to single tests. Keep changes small and targeted. When shopping, compare resilient options at zoa, hammer, and goby before buying.

Define your maintenance rhythm and document actions in the ReefBay app so improvements are measurable. Protect consistency by avoiding simultaneous major changes to light, flow, and feeding.

  • Adjust one major variable at a time.
  • Review photos weekly for early trend detection.
  • Use conservative stocking and acclimation steps.
