Yes Rick, there is not a real large flow into the Womb, and you have made good suggestions seeking to help the overall flow. It also may be a benifit to not suction as much of the sand out of the bottom of the Womb. There is a void down at the bottom that goes back under the cliff a ways. I have seen at times a white substance adhering to the rocks back in that area and it seemed to be something growing on the surface of the rocks, and not anything introduced by humans in to the pool. It looked kinda like white algae. Some people however like the pool deeper. I have not done real long soaks in the Womb for a while and I have had no syptoms of this rash as I had experienced in the last couple of years. Also I don't recall ever having those syptoms from soaks in the other pools, but I also tend to use the Womb mostly. Maybe at some point the culprit of the rash will be specifically identified. Until then we will just have to learn to live with what ever it is. You could do alot worse getting a sunburn down there at DCHS! Maybe we should ban the sun :-)
