well I've given it another go.. but not on my print that I really want to tone. Tried almost everything mentioned (haven't tried mixing it up with distilled yet) and got varying levels of 'fizzing' from mild to wild! Spongeing the print under running water gave me the best result (most even toning) but it still wasn't right. What I don't understand is I've used this before (same bottle, same paper) and didn't have any fixing or uneven toning.
