Pristiva

Hello pool gurus! I need some help - I have swam in a few saltwater pools and loved them! The water felt soft and left my skin smooth. I have a saltwater pool now but the water is not soft and it leaves me dry and itchy.... I found Pristiva and then read some threads here that sounded like it was not a good product - can you tell me what I might do to help my water feel great?

2nd question - I have a infinity edge and want to use some sort of liquid pool cover to retain the heat - any ideas or suggestions?

Thank you for your advice!!!!!
