I just set up my 18 AG for the summer and I have a couple of questions.

Here are the specs for my fill water from my well (I have a water softener)

ph
7.2
alk
260
hardness
0

After adding the correct amount of bleach and cyanuric acid, and running the pump for three days and aerating.

cl
3 ppm
ph
8.2
alk
260
cyn
40 ppm
hardness
0

I know I need to add some ph- to bring my ph down and continue to aerate.

My questions is why would after adding cyanuric acid would my ph go up? From what I remember from college chemistry acid should reduce ph.
