I agree that there were two problems here: the fixing, which caused the cloudiness (could have been badly loaded on the reel as well, i.e., touching), and the agitation, which causes the surge marks at the sprocket holes. For this latter, make sure your reel is not sliding up and down in the tank when you agitate and use the "torus" motion, i.e., twisting and inverting at the same time, and see if that helps.

You've fixed your own fixing problem :-)
