True. I have the flow going with the body of the clam. If it was against the body of the clam, lower flow would definitely be the way to go. Large clams Dont seem to mind as much. When my Maxima's where smaller they use to move away from the rock I had them on because the flow was going against the length of the clam. They have stopped moving now that they are 3/4 in
