Original I was trying to dose what one of those stupid calculators said to do to get to 8. It was like 20ml! I did that once and everything got mad lol. So I let it sit for awhile let everything go back down. And yup waited to long. Was at 7.5 a few days ago. I decided I would do 5ml a day till I hit 8.5. Obviously the tank is using it. I test every night around 8pm. Once I hit 8.5 I won’t dose that night and then check to see what it’s at the next. Depending on what that number is I’ll go from there.I'm trying to come up from 5.92 in mine... my tank is destroying alk...
