I definitely understand the issues around handling chemicals, I've worked in industrial and scientific chemical laboratories in the past, also have had smaller labs for my own use over the years.
From that experience is where I come to the sense that it could end up costing a fair bit to arrive to the necessary solution strengths during a 'finding out for yourself' exercise.
That experience is also what steers me in the direction of looking for the right vendor to do the work for me.
Having seen a few examples of recipe notes as seen above in the past which were also missing the critical information on solution strength I thought I'd ask.
Barrel Browner, what ready-made solutions do you speak of?
