The visibility was pretty bad (at least until we got to around 45 feet or so, and then it cleared up a bit.)

After looking at the pictures from today, I'm still seeing that I'm having trouble guaging distances underwater when it comes to choosing which macro lens to use. But when I do choose the right one, the pictures turn out quite well. Also remembered (can't believe I forgot,) that when the visibility is as poor as it was today, macro shots are pretty much the only kinds of pictures I should be attempting.
