Is it possible to neutralize the chlorine in a hot tub before using it? I figure if you can sanitize the water after using it and then neutralize it before using it, your skin wouldn't be absorbing all the harmful chemicals. I love my tub, but don't like soaking in the hot chlorine water with all my pores open and absorbing the chemicals. Other purification processes I have checked out are cost prohibitive for me. Any answers?
