Other parameter

In a reef aquarium

Nitrate is nitrogen nutrition for corals (zooxanthellae), bacteria and algae. Very low values can bleach the tank; high values promote algae and can upset balance. It links to feeding, stocking and export (skimmer, water changes, denitrification).

Quick tips

  • Use the same unit for reading and target (e.g. both ppm, both dKH for KH, or both ppt for salinity).
  • Volume = effective system water in liters (rough estimate is OK, but the cleaner the better).
  • This only plans increases. If you are already too high, the tool will not offer a “raise” dose: use water changes, media, or advice from your coach — not more of the same product upward.
