Thanks, I'll keep an eye out for them. In fact so far I've solved the 
problem by diluting the chemistry and increasing processing time. I halved 
the concentration, increased CD by 30% and bleech/fix by 25% and they seem 
to work well. Am I heading for disaster with this technique. The Images have 
the same colour balance as those done in full strengh chemistry.
