I would like help in understanding more about TA. In the old PF days, TA was pretty easy to deal with in that we suggested 80-120. Even then, if you exceeded these norms by a reasonable amount, say 60-160, it was not a big deal.
I know that JohnT successfully runs his pool at a very high TA (about 180, I think) because his fill water is well over 200. My TA in my fill water is 70-80 and I pay no attention to it.
Now, it seems we have developed different levels of TA depending on the chlorination device. I know the science behind it is valid but I am concerned we are overthinking the issue somewhat.
To those of you who have refined our suggested TA levels (Richard, Jason, Evan), could you help us laypersons understand that a little better? I suppose I am OK with the recommendation but I guarantee few here on the forum really understand it.
Please use short words and type v-e-r-y slowly so even I can understand it.
