We recently tackled lowering the CYA in our pool and my husband accidentally drained our pool overnight (leaving the pump on waste--whoops!). We refilled and our CYA is 0 now. I did pool math and am adding stabilizer granules. I am adding a pound each day (twice so far) because I'm afraid to overdo it. I still haven't gotten a reading yet for the CYA. Please let me know if this is wrong.
Our TA is 190 and the muriatic acid I got at Home Depot did nothing to change it. The only one we could find at our local store was their Green line and I couldn't find any indication of its strength. I'm guessing it's really low based on the pool not changing. I saw they also carry one made for pools at half strength. Can anyone recommend a place in Scottsdale AZ to get the 31.45% concentration (we are in North Scottsdale near Pima and Pinnacle Peak)?
