This really confused me as well. I bought the 20 roll kit and it only came with 50ml of the stab and indicated it needed 100ml for 1L stab. Everything else came with enough for 1L mixes. I was mixing 500ml at a time so I just used the whole 50ml for my 500ml mix (450ml water + 50ml stab). I just assumed that the whole 50ml would last long enough for 20 rolls. I have no idea what you would do for a full 1000ml mix.
