Hello, I run my Filter/ pump over night, every night. With Automatic Heyward Clorinator. In the morning when I test these are the readings I have: 0 total Alkalinity, 6.2 PH, 2 PPM Free Chlorine. When I test 2 to 3 hours later, TA and PH readings are the same, but FC then shows 0.
From my research, it seems that since the PH is very low at 6.2 and TA shows 0, this is probably the cause of 0 FC after a few hours. So my question is (also after some research), is it better to use Baking Soda to bring up the TA before trying to up the PH? In researching it seems to be that you should first try to up the TA because this in turn will up the PH. Does this sound correct?
