We filled our new pool, which finished in the late morning yesterday. We added the sequestrant and 2 gallons of acid. Pool water before adding anything was Ph 8.2, CH 200, TA 130. After adding chemicals Ph < 6.8, CH 150, TA60. My husband's pool friend came over they turned on the pump. 2 hours later, we heard a loud clank sound and pump turned off. Every time he tried to turn it back on, it tried then died. They think maybe the impeller (sp?). So anyways pump is not working. Our levels in the morning (this morning) were Ph 7.2-7.4, CH 125 TA 60. PH in spa 6.8. Per my husband's friend, we added 1 gallon of acid in pool, nothing in spa. We ran the grotto all day so the water wasnt just sitting. This evening's numbers are PH 7.2, CH 150, TA 30, spa Ph 7.8, CH 150, TA 30. Jandy technician will be here tomorrow afternoon, so hopefully we should have it up and running then. So our CH and TA is low. Will I need to add CaCl2 and baking soda? Thanks!
