You can select which days of the week you want to dose, along with how many doses you want per day and how much to dose per session. GHL pump programming is super simple, just pull up the GHL Connect or myGHL Cloud App and then you can calibrate each pump separately, prime each pump, and also program the daily dosing schedule within minutes. The 4 head dosing system is perfect for reef tanks that use methods like Triton, KZ, or Aquaforest that require more than the primary three additives. The built-in WiFi lets you connect to your home's router without any additional cables, but also has provisions for LAN or USB connections. Operate the 2.1 Doser from your phone, computer, tablet, or any other device that can connect to the internet. Not to mention that it has cloud connection with the free myGHL service, you can access and control your doser from anywhere in the world.

The GHL 2.1 Dosing System could be one of the easiest dosing systems to set up and run.
