My hot tub/spa has a white water line residue (calcium?) deposit and I am looking for recommendations on how to clean it off. I have used muratic acid in the past with little success.
The spa is always at a constant level as it has a spillover to the pool. Normal pump operation returns a portion of the filtered pool water to the spa and the rest goes to the pool returns. My calcium is currently at 325 but historically runs around 250.
I assume this white line is calcium but I do not have this line in my pool. It is also strange because my calcium levels typically run within the recommended ranges. Could this be something leaching from the concrete, stone mortor, or grout?
Thanks in advance!
