Guus Thanks... but I am using watter as a stopbath. After the 8 minutes in developer I remove the spool with film from tank and put it in a bucket filled with watter for about 1 minute ... agitating in the same time the spool with film. After that i place back the spool in the tank (cleaned tank - washed) and fill it with fixer...

Lucian,

in that case I would also suggest that airbubbles are the cause of your problem

Regards,

Guus

Lucian, bine ai venit pe APUG - I've been in your shoes for years i.e. developing with poor quality tanks but I avoided the corex system (instinctively, it never seamed safe to me). If you want I can buy and send you a Patterson tank with plastic spiral (double) where you can load one 120 or two 35 mm. I use the same and it works well so far. Send me a PM.
All the best

10x everyone for suggestions! Indeed there could be air bubles cought betwen film and corex band. I did not tap the tank considering the risk of cracking it, but the towel method seams a good ideea.
Nae merci si ti-am trimis un P.M. pe APUG
10x again everyone for helping me!

Just another thought...
My Rollei gives a series of little dots in the margin of any film, I think it's a pressure or mechanism thing in the camera.
If the dots are regular (in a line) I would suspect the camera is causing them. If they are in the margin it could be the film guides have sharp edges or burrs from wear?
I don't worry about mine they are in the margin so they make the camera more interesting
You could try developing a film without putting through the camera, ruling out that possibility and then send a film shot in the camera to a lab.
Welcome to Apug

Thank you Mark! I'll try sacrifice a film and develop it. See if the spots are still there! If they are then the developing tank is the problem for sure!

Might be the film. I had a bad lot number of Arista edu ultra 100 film (Foma) that had lots of white dots. Freestyle replaced the film. There is a thread on it on this site.

Other film bought the same time have fine results! And also the spots are aligned... something like a pattern!

I've read that Pentacon Six cameras do the same thing, but I don't own one so I can't verify this from personal experience. This shouldn't affect the image, though.

Sorry for huge delay...
meantime I succeded to scan some of the negatives I was talking about.
Here they are.
Thank you

I'd get a better tank, it looks like it's causing the problems and a new one will be far less expensive than ruined films in the long run.
