I am building a pool in Los Angeles that will be a NSP (natural swimming pool). I have the super-structure up to shotcrete and am at the step of waterproofing/adding coping/plastering. Looking forward to interacting with the community.
You will find that we are not a forum very compatible with NSP ideology. We welcome you to look around at how we do things, Pool School is one of the best resources available for pool care. Some of that might help you understand why we take the stances on pool chemistry that we do.
Regardless, good luck with your pool build and glad to have you!
