Juan,
If you're already giving the tank a good tap on the bench, especially
when the developer is first put in, then air bells might not be your
problem. Air bells will give you small discs of less or no density, but
you say you're getting dots. It could be insufficient agitation in the
first minute of fixing, especially if the stop bath is inactive. The
action of alkaline developer and acid fixer produces some gaseous
by-products inside the emulsion. With too little agitation to disperse
the gas the emulsion can rupture at that point and a small pinhole is
left which will print as a dark spot.
Just a possibility.
Regards,
Anthony Farr
