I'm relatively new to the world of spas. We got a small inflatable hot tub and loved it. SO much so that when a local pool & spa company advertised an end of summer sale we stepped up to a Viking spas Legend II. We are now at a crossroads. We are considering switching to using bromine due to three people in my house having chlorine/dry skin issues. I'm not really sure if our test strips will be the most effective way of maintaining proper chemistry not only through the winter but all year around. Does anyone know the prducts/methodologies that do the best and are most consistent in maintaining proper spa chemistry?
