this post will be a worthless review of apo reef because during my visit the viz was absolutely terrible. bad, bad bloom. very disappointed with that, but that's the (bad) luck of the draw. that said, on on the last of 4 diving days (4 dives per day), on the fringes of the protected area, we were greeted with decent viz, large swarming schools of jack, and surrounded by white tips on a spot picked up with sonar on the spot by the rags ii (although the plateau at about 30m, being some distance from the ranger station, had in typical philippines fashion been blasted in the past). the rags ii is an absolute class act for people who come to seriously dive.
