Reef Parameter Checklist

Reef stability is about patterns and context. Use this checklist to keep readings, equipment changes, and observations together.

Trend fields

Record enough context to understand whether a value is drifting, stale, or tied to a recent change.

  • Alkalinity, calcium, magnesium, nitrate, phosphate
  • Salinity or specific gravity and temperature
  • pH, lighting, flow, dosing, and water-change notes
  • Coral or livestock observations

Before changing anything

Use the checklist to slow down and verify rather than react to one number.

  • Retest surprising values
  • Check test kit age and procedure
  • Review recent dosing or equipment changes
  • Verify dosing decisions with product labels or trusted reef guidance
