Reef Directory Water parameters guide

Priya Nandakumar

Illustrated portrait of Priya Nandakumar
Owns the water pages

Priya came to reefkeeping through an obsession with water itself — she kept planted freshwater tanks for years before salt, and the habit of logging every parameter came with her.

Writes About
  • Alkalinity, calcium, and the drift that kills
  • Test kits and how to read them
  • Dosing without folklore

She maintains the site's parameter tables, cross-checks every number against published care ranges, and marks anything that varies between sources with a ~ rather than pretending precision we don't have.

“Reefs don't die of mystery, they die of drift. My job is making the four numbers that matter impossible to misread.”
