I'm not sure if I'm ready for this one. I'm very comfortable with pool care, and the TFP method for pools. I've read the different "How to's" in regard to Bromine or Chlorine.
Here's my dilemma: Until we moved into this house, with a pool, we had a hottub. I bought it off craigs as a fixer upper. The shell was in good condition and had no cracks or stains or anything. The wooden frame and enclosure were very rotten. Long story short, I was any to rehab it and enjoyed many years of almost daily use. In all that time I never changed the water, not once. I used neither chlorine or bromine. All I used was a copper based product, the built in ozone generator and MPS. That plus some pH down used once in while. Cleaned filter once a month. 4+ years that way.
So, if I decide to open the hottub box and set it up, I'm worried about the need to change the water on a regular basis. What is the thinking here? Is there a reason or is this another hold over from a time before we knew better? Like I said, I never changed my water. I checked it, using dip sticks, every week and would MPS it at that time. We never had rashes or smelly skin. Not one single issue in all that time.
I'm wondering if I was just lucky or what? What would be my best choice going forward?
