We've had our tub running for 2 weeks now. The water quickly became cloudy and very foamy. Today we brought the water in for a test and found that our TDS was over 4000. They said they had never had a reading that high and they normally suggest a water change at 1500. We then brought in our well water which tested at 2800 - still way too high to begin with. Calcium reading was also very high. Any suggestions on what we should do?
