Just got a Simma roller with a tank. I've never had or done any processing with tanks so I am a bit lost when it comes to loading the tank.
I will be processing film instead of paper.

It would seem the tank is designed to load more than one sheet but I don't know if I have all the necessary accessories.
The two white cylinders slide into the tank's ridges. There are three possible configurations (the cylinders can be slided in three different positions). What is the purpose of this? Different sized film/paper or 2/3 sheets at a time? Would I need extra cylinders/separators?

I also have this two pieces of plastic I have no idea what they are for. My guess is they work as separators so the sheets don't stick to eachother?

Also the tank was sold to me as a 24x30 but I've tried the paper separators that come in Efke 8x10 boxes and they seem to fit nicely (you can see one placed inside the tank in the picture attached)

Finally, anyone know how much fluid it needs to process 1-2 sheets?

There's little to no information online, thanks!
