Mixed my first 10-liter batch and the replenisher mixed completely clear with no residue, and the lower replenishment rate means I'm not constantly topping off. Prints came out with clean, consistent blacks even on a long run. This is the most economical bleach fix I've used in a while.

Ran my usual two 10-liter batches through the RA-4 line and the bleach fix held its color strength right to the last print. The low replenishment rate means I’m using noticeably less chemistry per week, which makes the cost per sheet feel like a steal.

Mixed up the full 20 liters without any clumping issues, and the lower replenishment rate means I'm not constantly buying more. Prints came out with clean whites and neutral blacks right after the first batch.
