Did a dive from P-1 to the first Wishbone jump via the Nicholson yesterday. Called the dive early (buddy had an equalization issue), swam back and did some of the short loops on the west side of the Pothole to P-1 tunnel.
It appears that condiditons are changing in the system, the stellar blue water that had been in the Nicholson/Cisteen areas a few weeks ago now has some tannic yellowish green color to it in areas, with some haze and particulate in the water column as well. Still totally diveable, just not the great viz. of a while after Irma.
