I've had my intex inflatable spa tub for about a year and a half and have been using chlorine with it. Recently my husband's skin has been getting very irritated after using the spa tub. Even when we swim in a hotel pool and hot tub, his skin gets extremely dry and very itchy from the chlorine. We are looking into doing a chlorine free/bromine free spa treatment and I found some good solutions. There's a company called BAQUA SPA. This would include BAQUA Spa sanitizer with stain & scale control, BAQUA spa oxidizer, BAQUA spa water control. Does any one have a chlorine/bromine free spa tub? Is it safe? Especially on the inflatable spas! Will my filterage system be fine going this route?
