We did P3 yesterday. Viz was 10-15 ft up to 900 ft of penetration. Quite milky, but beautifully spooky and mysterious. Looked like a different cave. We staged it and took a left turn at the T. It was crystal clear in there, unbelievably clear considering the first 900 ft.
Definitely worth the dive if you have fun with a bit of low viz, but I would not recommend it otherwise.
I am not sure why it is so milky right now, it could be the low water levels plus warmer weather.
