You mean you use the SAME toner over and over, and renew it every nine months?

Yes, although it does get murky after a while so I filter it through a coffee filter paper or kitchen tissue to clean it up. The toning times get longer and when they are so long that I get bored with rocking the tray I mix a fresh batch. A one litre bottle of toner lasts me quite a long time, several years in fact. I normally dilute 1 to 9 and have played with it at 1 to 4 at very high temperatures to get some very interesting affects but the fumes are really bad and play havoc with the chest and breathing unless you wear some sort of mask and work in a very well ventilated room.
