I am new to owning a pool. We have an Intex 12x24 pool. It has been set up for 2 weeks. We are using a SWG. All of my test are fine except pH which was 8.2 and TA which was 330. I used the "pool calculator" to calculate how much muriatic acid was needed. It suggested 52 ounces. I added 32 ounces and retested. TA was still at 275 the following day. I'm needing it at 60-80 with a SWG. My water looks great! It's not cloudy at all like many things I've read with high pH and TA. I run my sand filter for 6 hours and SWG for 5. Any ideas or suggestions would be appreciated!
