Hello,
My experience with SPA Balancer is exactly the same as your product description. The water is clear and clean, no smell, the pH value has flattened and become stable. I require neither chlorine and oxygen tabs nor pH-minus.
If one cleans the filter weekly and removes the initial lime scale from the pool, it is a superb article guaranteeing minimum maintenance.
I have attached older pictures from my Jacuzzi of a previous model.
