Hi bammbamm,

Yes, I am as sure as I can be without doing the testing. The testing was done by an ex-chemist in India; here is where the results are posted; you can review the entire thread or read the post dated Wed Apr 12, 2006 9:09 pm. It took me several weeks of Google searches to find that thread.

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!
