I can seem to find the answer for this. I use the Pool Calculator to get amounts to add for LC and MA. Normally I dont fill everything out but today I noticed the amount of MA to add changes based on the TA level (if I write TA as 60 it tells me one amount, if I put in 90 it says another). Why is that?
Also. Is TA suppose to be between 60-120. And CH between 220 and 320? I hear conflicting things here
Here are todays numbers let me know if you think all is on track
PH 7.9 (added to lower to 7.5)
