My husband and I are extremely satisfied with Silk Balance. Prior to Silk Balance, we used bromine. I would get out of our hot tub and have to slather on lotion. Husband stopped getting in spa because it set off his psoriasis. Now I’m able to enjoy the hot tub without have to put lotion on afterwards and hubby is able to enjoy our hot tub without setting off a bout of itching. The water feels great and there’s no chemical smell. Silk Balance saved us from getting rid of our hot tub.
