This is for the black P4 controller only - no probes. Power supply and USB cable provided. This works fine and has been disconnected from GHL Cloud. No problems and very little use on this. I had my main controller lose a temperature port and I had to send it in for repairs. Repairs were going...

Well, today is the day. I finalized my order and put a down payment on what will be my dream tank. I ordered a Crystal Dynamic Aquariums 225 gal tank along with metal stand. Below is what I plan on installing in the tank. Tank and stand: Crystal Dynamic Aquariums 225 gal 72x30x24 tank with...

The time has come to begin the journey with my next tank. I'm calling it the Acro Reef Home Office Build... Why? Well because it's going to be packed with my favorite kind of coral, Acros, of course! I will be running all GHL products. That includes the controller, lights, dosing pumps...

I have tried and tried to sync up my P4 to my KHD and Doser 2.1 to no avail. I downloaded myGHL and GHL connect and successfully created an IP address for the P4 and can now access it via WiFi but when I went to connect the Doser via Static IP it would not accept any IP address. I was told that...

Recently got the GHL KHD at the first measurement I took read 11.8 when my Hannah checker reads 9.5. I use reef crystals with no problems and have a hard time believing that my tank is running at 10-11DKH. I contacted GHL and they basically said that Hannah is cheap and not as accurate as the...

Hi All, I am planning to setup Profilux Mini Wifi on my Nano. I just want to know if I can add one more STDL4-4 unit to the controller. I am aware of it from the pictures that it has only one port for connection. But is there any splitter or add-on/daisy chain that GHL provides? Also, if...

Hi there, Ive opened this as a ticket with GHL, but hopefully you might be able to shed light on what I’m doing wrong. I have been controlling two Tunze 6040 pumps with my Profilux 4 using illumination channels and it has worked fine. Today I added two more 6040s as well as two Stream 3s. I...

I decided to start making some helpful processes in layman's terms for other fellow reefers. I decided to complete this process through GHL Connect vs. Control Center (I'm a Mac user and prefer to do things without having to touch Windows if I can help it). I hope that you guys find this useful...

Need your help... I have two 300w heaters in my sump. I want to keep the temp fluctuation in the tank between 77.5º and 79.5º. I'm using the Cobalt Neotherm heaters. I can set them to 78º or 80º (nothing in between). My questions are as follows: How should I set up my P4? Should I tell it to...

What am I doing wrong? When I add an event in the logbook, it's showing tomorrow and a time that's clearly not the right time. How do I sync the times?

So, I want to connect my return pump to my Profilux 4 and am going through this thread: Howto: 0-10v Control Return Pump. I have some questions, though. This link is no longer available: GHL LBF-AP module and it says I need it to connect my pump. Can anyone out there point me in the right...

Before I updated to the new firmware for my profilux 4 last night, I saved the sensor and settings data to files (as is recommended by GHL). The firmware update went well. I imported my saved settings and sensor data files and everything looked normal. Though I didn't check any settings or...

Hello all, I picked up some T5's to supplement my Kessill 360x lights. I'd like to have the T5s ramp up and down with my LEDs so I bought a GHL break out box which connects to my controller. I can't seem to figure out which wire goes where from the T5 ballast to the breakout box. Any...
