While anything acidic will burn off some carbonate alkalinity, people have different preferences for their TA. The key point is that you need to keep your pH in the right range, and the TA acts as a buffer to facilitate this. Find what works for you and go with it. There are as many opinions on exactly what your TA should be as their are pool owners.Plain wrong here. TA for unstabilized chlorine like bleach or a SWG should be 70-90 ppm. For stabilzied chlorine it should be higher 100-120 ppm.
