Thanks for all the insight. I have the same problem with my wife as well.
Major rash and itchy as I have none.
Been fighting to keep the sanitizer maintained. Really had to wack it with alot of spa shock and thinking that this is possibly her issue.
Looks like a drain and fill is in order.
Getting alot of foam even though the water is clear and you can smell alot of chlorine when you open the lid.
Learning curve definitely with a new tub. Use to a a 16 x 32 pool .
Had a phosphate issue and that took a bit to cure.
Thinking maybe that is where all my issues started from.
Regards
Steve
