GHL KHD questions

[Coralqueendom]

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 GHL which I believe is true but I don’t want to adjust my system to 11.8 if it’s not really that. I ordered reference solution but not Sure how to use it yet I’m sure I can figure it out once it gets here. I know you can adjust the disparity between the testing method you usually use and the GHL but if the GHL is really that much more superior in accuracy than I would prefer to adjust to its levels. I also I’m having a hard time figuring out what adaptive control motors and how to properly set up a dosing schedule so I can completely control my alkalinity.

KHD 7.5 Reference Solution

Hi everyone, Stupid question but how do you use the reference solution? Do I just hook the bottle up to pump 1 and run a test? I just got my bottle today and want to put it to use this weekend. Thanks in advance!
