My last few runs with HC-110 showed a significant amount of foam once I opened up the tank to pour out the developer. I'm curious to know if that's normal. Any other users report seeing foam after all your agitation? This is with just dilution B in the tank and nothing else (aside from film; HP5).
I wash my Patersen tanks until the rinse water does not foam at all so I'm pretty sure that there is no soap residue left over from the cleaning stage of the last development run.
