Thanks Aggie, thanks Ole..i did what i thought was adequate stirring whilst adding C but i guess maybe not enuff...i did make a VDB liam lawless contrast control mix (mention in PF #8 i think) mix too with ferric citrate in the A and that bottle looks completely dissolved, even the ferric citrate seems to have dissolved overnight on that one..i guess i'll keep stirring on the classic and hope that it dissolves.

BTW: does it matter what kind of lighting conditions you do the mixing under? does it need to be subdued lighting or is the mixture not sensitive at this point?
