@skinnylatte The Paterson tank never leaks, excellent choice. The sleeve saved me from the need for a dark room, but you can also use a thick coat..for black and white film developing products, Rodinal is a very old formula, but a little grainy. I switched to Xtol, less toxic and thinner. For bw film, Fomapan 200, but also the 100 and 400. Don't forget the clothespins, white vinegar, dishwasher rinse aid, salad spinner, laser thermometer, kitchen timer, the hairdryer...
