I bought a few packets of Fujifilm Microfine developer but there seems to be a problem with it. I mixed it as follows: "While stirring 1 litre of warm water (50 deg C), pour in sachet contents gradually. Keep stirring until completely dissolved. Use complete sachet contents at once." The problem is that I am left with a cloudy stock solution in which there are many suspended particles that don't dissolve, even though I followed the instructions to the letter and left the stock to dissolve for a day or two. The expiry date on the packet is 11/2011. I've now wasted two packets on this and have only one packet left. Has anyone else had this problem with Microfine? I have no problems with dissolving other developers (D76 / Xtol etc.). Maybe because I have hard water?
