I'm upping my testing game. I'll soon be in position to do these things like a pro. I now have a pH meter instead of testing strips. I ordered a total acid test kit...be here on Thursday I've always had a hydrometer. The last thing I need is a way to monitor MLF. How can I do that? If the pH is where I want it but the acid is not, what does one do? What if the acid is proper and the pH is not?
