Hi! I'm really excited to have found this forum and hope that my first post includes all the necessary information...
We have always had high TA, but our other numbers have been good and the water has always been clear and nice looking. This is the second year of us having a pool and we are still using shock, but want to switch to the BBB method. We have hard water where we live, so would that have anything to do with our high TA levels? The pool store wants us to use "Metal Magic", but we have always tried to use minimal amounts of chemicals, so we haven't done that. Do we really need to use "Metal Magic" or should we try to lower ph in order to lower TA? How serious is it to have high TA levels in the long term? We have a vinyl pool, so that should help a little, right? Also, is it possible to simply switch to BBB in the middle of the season or are there some issues we should be aware of?
We just used the TF-100 test kit for the first time with the following results:
PH - 7.5
FC - 6
TA - 180
CH -390
CYA - 50-55
