We are finally at the point that some of our corals are showing real growth, and have noticed a drop in our dKH. As I adjust our Kalkwasser and two part, I would like to check my dKH more regularly, every day. Does the level change during the day or is it more or less constant? I run my Kalkwasser in divided doses from midnight to 7 am and the two part in divided doses from 7am to noon. My lights run from 1pm to 11pm and the light on the refugium all the time.

Alkalinity only declines between doses. So the timing doesn't matter as long as you know how it changes between doses.
