Ghl doser?
 

What is the smallest increments that can be dosed with the ghl dosers?

Also is it safe to mount the unit in a vertical position, with the pumps facing down? Asking because it would be easier to read for me this way & don't want to damage it.

I have mine mounted vertical no problem. Smallest increment is 1mL.

Thanks is there somewhere I can actually find some kind of guide for setting this thing up? I just managed to set the time and date, I think, if the settings are D/M/Y right? I'm honestly a little bit nervous to go much further with little experience with this kinda stuff.

DITTO!

It's very easy, if you use the automated settings.

just pick the pump (1,2 or 3) tell it how many times a day to dose and how many ml's per dose. Done!

Here is the support forum for the doser:

I'm just setting it up, & can't even get it to move water ??

It takes a while for the pumps to draw the liquid completely the first time. just hold the red button next to the pump until you see the liquid coming out the end.

Search the forum I linked above. All the answers are there.

I had to fill about 6 or 7 feet of line before it reaches the tank. Might have to hold the button for a minute or more. Remember to calibrate. The included instructions are short but the unit is very simple and quick to get going.

I'm pumping up about 3'6" & it's delivering 43ml P/Min on pump 1, about 41 on pump two. So that's very close to 70% .
