Recently I've been experimenting using directly a 250mg potassium permanganate tablet, bought from my local pharmacy, as a bleach, acidified as usual.
This way is much more simpler: no need to stock concentrates, I diluite ONE tablet per 250ml immediately before using the bleach, so to have maximum consistency from run to run.
