<p>@Bethe - Thanks for the offer on the stainless tanks. I want to try a few more things. I should add it's only the top reel that has the problem with foam marks, and it's only the combination of Acros and HC-110. I like this combination and want to make it work, but I'd also like to do two films at a time and not one.</p>

<p >Thanks. I tried to word my post so that it didn't go down the worn path of "which agitation is best." Suffice it to say my inversions are SLOW and GENTLE, and I rap the tank hard several times. I'm using the taller Paterson tank that hold two 120 reels. I believe inversion is best, and for other combinations of film and developer that I use, it's fine. But when it's not, I'm wondering if lateral agitation (in a tank not filled to capacity) is sufficient to move things around. </p>

<p>In general, what are your thoughts on lateral agitation? In particular, I mean agitation that involves moving the tank from side to side and/or in circles but never tilting or inverting it. Figure 8 agitation is one such technique, whereby the tank is moved vigorously along figure eights on or off the work surface. I'm having a problem with foam that seems to be alleviated only with lateral agitation. I've read it can cause problems with 35mm sprocket holes (I've only done it with some test strips of Acros in 120). And in general, I'm wondering how effective it is in delivering fresh developer where it needs to be. Thanks.</p>
