Im assuming you were the one with GLOC on the tins and on the undersuit ?
Got kitted up right next to the 3 of you in the afternoon and were one of the last to leave (parked next to us).
Vis varied from perfectly acceptable 5-8m or so to 1-3m where people had kicked it up. Could tell you were nearing an attraction as a wall of hanging silt appeared in front.
Not sure what it was but something that looked like larvae/eggs/spawn of some sort in the first 3-4m of water.
