Or use the ring clip on the column to hold the reels down, if you have one. Not sure every Paterson tank came with one of those clips.

That's a good idea. I don't I ever had one of those, but something could be fashioned very easily, even if it's not an official part.

It depends on which version of Paterson tank you have.
I use empty reels instead - but I have enough extra reels.

It actually does works extremely well on the old Paterson System 4

I always found the clip at the top when I opened the tank. The reels were down but evidently the top reel likes to spend time at the top.

Check the pH, the developer could be coming more basic if it is feeling soapy.



The point was that solutions that are basic react with the lipids in the finger skin and turn into soap yielding the "soapy" or slippery feeling. Biochemistry, not Photochemistry.

Developers are all basic/alkaline with the exception of one or two amidol formulae. As a result they all feel smooth and soapy.

That is what I thought. Although I would never use pyro without gloves, would pyro feel soapy?

My Paterson instruction sheet mentions not to tilt the tank when filling.
Keep the tank vertical as uneven development may occur otherwise.
The tank is designed to fill rapidly from the bottom upwards.

I do not know if uneven development covers bubbles, but every little thing helps.

The leaflet also mentions immediate use of the twizzle stick to remove bubbles at the begining of development.

Mention was made in a magazine years ago of using a piece of plastic plumbing pipe cut to the appropriate length, then placed over the reel supporting column to keep the reel from riding up the column.
