What kind of doser do u use?

let's say you want to on-the-spot add say 60mL to make a larger adjustment to the reef.

GHL gets my vote. I like it so much that I now have two.

I use the Drew's Dosers from BRS, but different from the BRS brand.

I've been using the GHL stand alone for about 4 years. Love it!

I'm stuck using an aqua medic quad. Someday I will save up more pennies and get something better, although to be honest it's working well for me despite the bad rep they have.
