Thanks everybody for the answers!

It looks like that the two reels option is what I should prefer, for the time being. Since this is my first attempt at developing BW on my own, I think I can stick to one single tank for now. If my experience is successful (and my family won't complain for the mess in the bathroom ), I might consider your advice of adding further tanks.

Just to share what else is in my cart:

  • Rodinal 500cc
  • llfostop 500cc
  • Agefix 1L
  • Agepon 250 cc
  • Paterson Thermometer (Alcohol)
  • Graduated Cylinders (50cc and 650cc)
  • Kodak Tri-X 400 (5 rolls)
