Simple & Smart Dosing

The GHL 2.2 Dosing System is one of the easiest dosing systems to get up and running. Control is easy from any smartphone or PC with the WiFi and USB connection. With the free GHL Connect App, the myGHL cloud service, or integrated web server, you can access your Doser from anywhere. Aside from being a reliable automated dosing solution, the Doser 2.2 can also keep track and control the liquid levels in your dosing containers, alerting you when the minimum level has been reached.

Straightforward Programming

GHL pump programming is simple. Just connect to your Doser using your preferred method and you can calibrate each pump separately, prime each pump, and also program the daily dosing schedule within minutes. When determining the dosing times, you can either have the Doser automatically spread the doses evenly throughout the day (up to 150 doses) or individually distribute up to 8 doses per day at specific times of the day. New to the GHL Doser is a continuous duty mode for those who may want to use these pump heads to feed small reactors or doing a continuous supplement drip.

Powerful & Precise Flow

Having speed control of the dosing head is critical for some additives like alkalinity solutions that can easily precipitate if added to saltwater too quickly. The variable flow rate dosing heads can push anywhere from 8-45 mL per minute and can be programmed through the GHL control software allowing you to dose solutions accurately to 0.1mL. The rate of flow can vary depending on the length of tubing and head height required. The max distance the GHL 2.2 SA Doser can push or pull liquids is 50 feet of total length allowing you to put the dosing where you want it, and then route the tubing to your vessels and sump.

Expandable

Need more than 4 pumps? Connect a GHL Doser 2.2 EXT or Doser 2.2 Maxi EXT to add additional pump heads that can be controlled through a single interface. The Doser 2.2 EXT or Maxi EXT will need to be connected to the Stand-Alone Doser via a PAB cable (purchased separately). The additional heads can help keep your reef tank much more stable by automating other additives that would typically be dosed by hand. A maximum of 16 dosing heads can be connected together. 

LED Status Display

The LED-backlit GHL Logo in the housing cover serves as a status indicator. Various colors show you, at a glance, the condition of your system.

White = Configuration mode
Blue = Normal
Green = Amount of liquid in the container is OK
Yellow = Warning threshold amount of liquid undershot
Red = Alarm threshold amount of liquid undershot
