My alk from the ATI ICP test has been consistently about half a point under my Hanna Checker. Hanna is showing 8.0 and typically the ATI would be 7.5.
The latest test I just got the results from show it a full point under at 6.8 somehow - difference this time being it took a few extra days to get to Germany in the mail.
With a salt that mixes at 8.0 and 15% weekly water changes in a 20 gallon tank - wouldn’t it be nearly impossible to be at 6.8 unless I was dosing something acidic and not countering it?
I also have very little consumption - maybe drops 0.3 in 2 weeks if I dont change the water.
