ghl

Hi all, I've had my GHL Profilux P4 for about 2.5 years. As I understand it, pH sensors last 1-2 years. Is there a way/test to tell if the probe needs to replaced? (Rather than just replacing it outright just because it's 2 years old.) Thanks!

Hello I looking for GHL sa 2.1 doser

Hey guys, So I am just curious like in 2021 what most people are using to control their tank if anything

Morning all! Was curious about two things... What categories do you guys have in your logbook. Curious as to how you all categorize everything (bonus points for sharing screen shots). What does your dashboard look like? Do you have a different dashboard for MyGHL than you do for the dashboard...

I have some programming questions. I am thinking of improving my RODI unit. I am thinking of buying 3 more solenoid valves to plug into my GHL powerbar. I already have one solenoid that turns on when my auto top off water bin is low. It is connected to two float switches. My solenoid...

Hi all, I'm not at the point where I want to automate my alkalinity dosing. I'd like it to be as hands off as possible. :) How is everyone liking the GHL KH Director? Thanks, lylelovett

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 Is it just an older model or is it completely outdated.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?

Hello reef family am selling 3 GHL MITRAS LX 7206 in black there absolutely nothing wrong with them i’m just an equipment junkie I want to try some new lights PCW BOARD WICH GO INSIDE THE P4 for Communication with the controller and the lights ask $60 shipped once’s I have sold the light Ask...

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...

Why didn’t ghl ion directer and the kh directer just merge into one unit so u don’t have to buy 2 units for tank automation like the Neptune trident come on ghl get it together

As the title says looking for a GHL Profillux 4 and other products - must be located in the UK
