Welcome to our forum.
I had some itching and rash problem and my dealer put me on the Leisure time Free system and it helped! Maintenance was an easy once a week treatment and wash you filters. The water stayed clear and felt soft for 5 months and then you could tell it needed changing. The cons I found was when you turned on the air jets the water would look milky and would clear as soon as you turned the air off and let the water dissapate the air. The other issue was that there was a effervescence like alka seltzer when the air was on. Cost factor didn't seem bad:I Control 16.99II Boost 7.99III Free 17.99Total 42.97 for 5 months and there was some Control and Boost left over.Good luck!
[Hmmm. Do you have Ozone? I wouldn't be opposed to trying such a system, (I've got very sensitve skin). But the "incompatiable with ozone" that I read about Biguanide put me off.
