Stable Alkalinity. Healthy Corals. Automated.

Manual testing can’t catch rapid alkalinity swings. The KH Director® monitors and controls KH levels continuously using direct titration—the same method professional laboratories rely on for accuracy.

Choose standalone operation with integrated dosing, or integrate into your ProfiLux ecosystem for synchronized control of all reef parameters.

System Options:

  • KH Director Standalone (works with GHL Doser 2.x / 3.x)
  • KH Director EXT (for ProfiLux® 3 or 4 + Doser 2.x / 3.x EXT)
