I'd say 98% of them got sucked up in the overflows and taken out with the filter sock. By the time I went to bed, there weren't any more bodies left in the water or visible on the rock.
I also filtered with carbon for almost an entire day. I guess my real question is whether or not a sudden drop in phosphate levels will cause polyps to close up, because if not, I need to do a whole bunch more water changes.
