Questions about AP develop tank

Stefano Bramato wrote,

The agitation that I do is gentle but firm:
hold the bottom strongly with your hand and turn it upside down gently
but
constantly the x times you decided. After that, to pdiloge bubbles
created
inside tha tank knock your tank against your lab table.

Ddi you mean you tap the tank everytime after an agitation? I often
see people on the forum do the tap only once just after(or before) the
initial agitation. Which method is better? It should be a
consequence that agitation itself can produce bubbles if tap tank is
necessary in every agitation.

yes.
I tap the tank everytime after an agitation or inversion, it is necessary
because everytime you do inversions, everytime you are making bubbles...
simple!!
IMO

I'm not sure. It definitely seems to work better with the older style
Paterson tanks. Maybe the air pressure from putting the top cap on
quickly breaks the seal between the tank body and the lid.
t is certainly worth a try.

apr705 from Lloyd Erlick,

It is a bit of a weird thing (not to mention weird to
be talking about such a thing with other adults ... !
We really have to be thankful for rpd, our friends and
relatives wouldn't stoop to this.)

I've always thought this weird phenomenon happened
because the fast-push of a plastic lid onto a metal
tank left some of the contact area between plastic and
metal dry. A slower push, or better yet, a kind of
sliding, twisting, up and down seating of the lid onto
the tank, made sure there was some liquid between the
materials to act as a seal (or would sealant be a
better word?). In any case, I always found the whole
thing went smoother and worked better if I wet the lid
before I put it on the tank.

But I've found the ideal method (for me). I use lidless
cylindrical tanks in the dark. I fill them with
solutions and turn out the lights, and develop ten
rolls of film by lift-and-lower. Very restful, no
lifting of heavy jugs of liquid, peaceful trickling of
water in the dark ...

regards,
--le

Yes, you should see Lloyd's luminous, saucer-sized eyes. Actually, he looks a
lot like Gollum, from all those hours in the dark ...
