Welcome to our forum.
Ibut I believe it's the water balance that is probably the biggest factor on whether she has issues.
Without any knowledge of the sensitivity issue, this is probably a fair statement. I use chlorine but put in a dose when we get out and the tub is almost 0 ppm the next time we get in.
How's this fart going to get into the tub between the time he gets out, and the next time he gets in?
Footie .. my question was an attempt in getting opinions of two filtering systems and if I could get by with less added chemicals with one over the other. I am very aware of the need for proper ph and sanitation. I guess we won't really know until we try both chlorine and bormine to see if one works better for her than the other. thanks for your reply, my wife found it reassuring that she isn't the only one out there who has had negative reactions to pools and spas.EJF .. Can you comment on Ultra Pure vs. Ultra Pure Plus .. The salesperson had a blank stare when I asked him for his opinion.
