It is a fresh mixture, so may need to "ripen".
And yes, I am comparing work done in different locations, so possible water pH is a factor.

One question, did you let the VDB solution ripen?

I suspect the water supply pH or minerals may be involved. I am having slight changes to my VDBs depending on where I process them. At school they seem to dry down a lot more and give me a very strong brown background compared to the ones I make at home.
You may also wish to experiment with shorter fix times or changing your dilution of thiosulfate. I am using a 30g per liter solution.
I don't clear with citric acid but with Sprint Fixer remover.

I've recently been using VDB again but with different results than I've had in the past.
I made up a fresh batch of the VD and am using fresh thiosulphate, the results are not a strong brown and there is weak contrast. When I first rinsed the contrast was good but that was quickly lost. I did try pot. dichromate but that didn't do anything visible to the contrast.
Any suggestions would be appreciated.
