Yes, you are correct. 1940 ml of water plus 60 ml of 50% Glut will give you 2000 ml of a 1.5% concentration solution.
I use the Glut as an algaecide in conjunction with my 30 ppm CO2 measured with 4.0 dGH indicator solution in a drop checker. Glut, like Excel, seems most effective on the "soft" algae types.and has some however minimal effect on GDA, GSA, or BGA. My plants seem to like the extra carbon!
Thanks a lot for your detailed reply. I'll start dosing 20ml of 1.5% Glut solution at my 800l tank daily (100ml after water changes). My tank's KH is 3, and ph-controller set to 6.42-6.48 interval, so I'm injecting slightly more than 30ppm CO2. And the current setup is 1 month old, we'll see results
