Anon Frens, Borax solves the chlorine problem. Research it Anons. Borax DOES SO SO MUCH. I have stopped using chlorine in my hot tub and replaced it with Borax and my tub is WAY BETTER. Not only that but if you do some digs you will learn that Borax is bigly NANO INHIBITER. Yeah there is that shit too. Borax is cheap and easy to buy.
