When I developed FP4+ I put 2 rolls in the same tank. One came with the marks, and the other not. Both rolls got the same soup, same water, same final rinse. So why one has the marks so consistent and the other is so clean?
Because one was on top, where all the bubbles of the frothing 'soup' are, the other below, fully submerged.

Put more liquid in the tank, and use less photoflo (and rinse the tank and spools thoroughly before using them again).
