Hi All, our 8000 gal., blue, quartz finished pool was completed over the summer and for the first 4 weeks as instructed, we took our water to the PB and they told us our water was great. Our house has a water softener that I installed in time to fill this pool, since our city water is hard but otherwise fairly balanced, this is our 4th pool with this water supply. We use the TF-100 Test Kit and the Pool Math app suggested by this community. After the 4 mandatory weeks of the PB testing, they released it to me, I noticed the CH was very low, so I added 22 lbs of Leslie's "Hardness Plus" calcium chloride as directed and brushed it around. About a week later, the spots started to appear. This is about 6 weeks after the pool was filled. Below are my weekly readings, and I only added muriadic acid until the chlorinator was installed, then also added dry stabilizer and calcium chloride as calculated by the pool math app.
It goes without saying, our PB is refusing to work with us on an acid bath, or any remedy to clear the spots, they're telling us it's scale. Told us our CH was over 500, even though my test and Leslie's puts it right at 300. They sold us $80/10lbs worth of Jack's #2 copper and scale stuff, and gave us polar opposite directions on how to apply it compared to the instructions on the bucket. Also said it will be good for our heat pump, even though according to "Jack's" instruction is to isolate the heater, but of course they didn't install a heater bypass.
So do you think all this is because I added the calcium chloride? What if I didn't sweep it around enough?
The PB gave us test trips to use, so while the water testing was under their care, I didn't use the TF-100
