About this app

GHL Connect allows you to monitor and configure your ProfiLux computers, Mitras LX 7, Doser 2 or MaxiDoser with your smartphone or tablet in a very easy and comfortable manner.

Connect directly with your GHL-device; it does not need external resources or an internet connection if used locally.
You also have the opportunity to connect easily with myGHL in GHL Connect to access your GHL device via the Internet.

GHL connect helps you to check current states, alarms and activities and allows you to edit most settings and to start special actions like manual dosing, water change, thunderstorms and much more.
When you connect GHL Connect to a myGHL account, you also have the possibility to share your settings and the customizable dashboard across all GHL Connect platforms with CloudStorage and the possibility to view sensor charts over a long period of time.

I've had a Doser 3 SA and Doser 3 EXT for a month now. I have to cycle power every day to connect to the doser. The application screens to calibrate the dosing pumps and enter the amount of liquid in each reservoir make no sense. For example entering data in one field labeled maximum changes to "min" when saved. there is no provision to label each pump with the chemical names being dosed. I cycled power once and all of my calibration settings were lost.

Probe History doesn't work after firmware update. I created a ticket yesterday and still have no response after 24 hours. I have a 700 gallon acro tank, so the lack of response to highly invested customers is overwhelming, to say the least. 10% of my coral have died while I wait on an answer

We're sorry about your corals — we know how much is at stake. To clarify: your ticket got a first response within 30 min and was resolved in 26 hours. Your other open tickets are being actively worked on. We're on it!

Awful customer service, dashboard crashed over a month ago. Ive sent multiple emails someone responded to the first with basic solutions to which I completed and also asked for the crash report. So i sent it 3 different times. Also asking for more options because nothing worked. I have never heard from them since. I have no access to my doser and no solution to fix it as well as no response. I hope that people do some research on ghl before buying this purchase is the biggest mistake I made.

Hi Ryan, I regret the experience you describe. I invite you rather than sending emails to open a support ticket here: https://www.aquariumcomputer.com/support/tickets-enquiries/ (Guest login) We will be happy to help you with your doser.
