Color Reversal Bleach Starter 4 x 2L Concentrate

The four 2L jugs are a solid bulk purchase for any lab that runs E-6 regularly, and the lower replenishment rate genuinely cuts down on how often I have to reorder. Mixed the concentrate without any issues and the bleach held up perfectly across a long session.

I was a bit worried about mixing up the concentrate ratios, but the lower replenishment rate means I'm going through way less chemistry than with my old setup. Even the first batch came out perfectly clean, with zero color crossover on my test strips.

The 4x2L format is perfect for my lab’s volume—no more mid-week reorders. Mixed a batch last night and the bleach took hold cleanly, with lower replenishment than what I used before. Just wish the concentrate came with a measuring cup, but the consistency is worth it.
