I've made many hundreds of cyanotypes in central Florida where the water is quite hard. After testing many papers, I've settled on Arches Aquarelle water color paper as a decent paper that gives good results. You should be able to find that readily. I add 1/2 gram of oxalic acid (wood bleach at the hardware store) to each 100 ml. of solutions A and B to help counteract the effects of alkaline water. Have you measured your water's ph level? That would help offer meaningful advice and allow meaningful comparisons to other's working conditions.
