This Chemistry Thing

[Enigma]

Chemistry has never been my strong point. I'm much more of a physics girl. I've been trying to get a grip on how parameters affect and relate to each other, but the old grey matter is just not puzzling through this.

I was doing my testing last night, and I was very pleased with the numbers I was getting: until I got to alk.

If I do something to increase my alk, what will that change? I would really like to avoid dosing . . . but I'm sceptical that I can. I don't want to get caught in a dosing spiral, where one thing is being dosed to be corrected, and another three things are being dosed to correct wonky values as a result of the first dosing.
