Dropped off boat onto reef and finned out into blue keeping reef left shoulder. Light current. Descended to 36m. Saw a Manta above us at about 20m – a big one! Made our way back to reef and current changed in our face – medium. Turned around and slowly ascended up wall. I got a deco warning at 25m. Slowly ascended and finished safety stop in the shallows with batfish, white tip sharks, zillions of turtles, lionfish and a really nice sea cucumber. Great dive!
