Hi, I have an opportunity to buy a GHL 2 dosing pump for $160. I was wondering if this is worth it? I know there is a 2.1 out now and I can’t learn too much about the 2.0. Is it just an older model or is it completely outdated. I am just looking to dose calcium, mag, and alK. Thanks all.

Hello reefers, With my current tank slowly leaking, this has put a hold on stocking the tank. The tank is leaking from the bottom left corner. Thankfully the guys @ Crystal Dynamics Aquarium replaced my aquarium and provided a new Stand ( warranty 2 months shy of expiring. With the pandemic in...

Maxi doser stock seems to be out for weeks. Any idea when/if there will be more available?

Currently have four AI Hydra 26's, thinking of purchasing a GHL hybrid fixture which accommodates four T5 bulbs. Looking for guidance on bulb color recommendations to compliment the LEDs. Any recommendations?

If I purchase a GHL Doser 2.1 standalone unit now and decide to purchase a Profilux controller in future, i'm assuming the standalone unit could still be managed just the same as the slave?

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 GHL home office build... Why? Well because it's in the GHL home office, of course! Here is where I will be running all GHL products. That includes the controller, lights, dosing pumps, automated test stations...

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...

Hey there everyone. Trying to access the Logbook on the GHL app via iOS. What am I doing wrong? Any help is appreciated.

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...

Looking through all the threads...GHL P4 has changed quite a bit! I initially had to set it up using a Computer with Windows installed. The computer I used crashed and I can't access it any longer! Question...How do I transfer these settings from my P4 to a new laptop without losing all my...
