Chlorine is a very bad idea. It could cause the springs to be closed. The area is habitat to protected trout and arroyo toads. If our use is seen as jeopardizing these species, we will find ourselves without a hotsprings. Please do not use chlorine down there. We just have to encourage people to behave better and/or provide someplace where people can use the bathroom easier.
As far as Asians arriving and not understanding the local customs, this is a public hotsprings. Clothing is optional not nudity is required.
