KH Guardian Pro Alkalinity Controller

The KHG is an all-in-one device that automatically monitors and manages the carbonate hardness values throughout the day. Such a tool is often considered "the holy grail" and can dramatically simplify and improve the way we manage KH parameters of a reef tank.

A must for dedicated reef keepers

  • Test accuracy is +/- 0.1dKH
  • Automatic tests carbonate hardness levels directly from the aquarium
  • Manages your KH levels throughout the day, resulting in rock-solid stability
  • Continuous monitoring and data recording
  • Built-in memory for long-term data logging
  • Easy to read LED display
  • Compact, easy installation and simple operation
  • Bio-Safe reagent can be dosed back into the aquarium
  • No software or APP needed*
  • Dimensions: 7.75" long x 5" wide x 9.75" high
  • *The KHG does need a home network to work

Introducing KH .'s Revolutionary Guard

The KH Guardian is without a doubt one of the most innovative, exciting and ultimate game-changing reef aquarium products of this century from the brilliant minds of Dr. Bridge. The KHG is an all-in-one device that automatically monitors and manages a reef tank's carbonate hardness values throughout the day. Such a tool is often considered "the holy grail" and can dramatically simplify and improve the way we manage KH parameters of our aquatic investments.

What is Alkalinity (KH)?

Alkalinity is a means of quantifying pH stability in aquarium water. It is a measure of the concentration of various negatively charged ionic compounds (anions) such as carbonates, bicarbonates, borate and hydroxides in the aquarium water. While it is a simple and affordable test, it takes user error and time out of the equation so one can rest assured that their reef aquarium is safe and stable.

Why is alkalinity essential?

Alkalinity conservation is a critical aspect of coral reef aquarium farming. If left unchecked, the alkalinity can drop below a critical level and the pH begins to fluctuate more wildly than the suggested +/- 0.2 daily pH shift for marine aquariums, causing stress for livestock. In a marine aquarium, the desired alkalinity is usually between 7° and 10° dKH (German carbonate hardness).

KH Guardian makes it possible to monitor buffer capacity and automatically manage the KH levels of your aquarium water in a simple all-in-one device.

KHG Features

  • The resolution of the Standard Edition is 0.1 dKH.
  • The accuracy of the continuous measurement test is +/- 0.1 dKH.
  • Measuring range: 5 -12 dKH.
  • Use only one reagent for each test. The used reagent goes directly to the aquarium without any safety concerns. Each test only takes about 3~4 cc. reagent.
  • Automatically calculates how much sodium bicarbonate solution should be added to the aquarium with the reference of the desired dKH target value, the total aquarium water volume and the current test value. Then the controller doses the sodium bicarbonate solution accordingly.
  • Automatic measuring interval adjustable from 30 to 240 minutes. Each measurement takes approximately 3 to 7 minutes.
  • Use in conjunction with an existing calcium reactor and other automatic alkalinity dosing methods. We recommend lowering your current dKH dosing parameters slightly below your desired target, and let KHG do the final fine-tuning for your tank automatically.
  • Dimensions: 7.75" long x 5" wide x 9.75" high
