What span of time is there between your testing? When you test the alkalinity high, what do you do to fix it?

I've been testing alk every night at the same time. When it doesn't get consumed, I unplug the alk and calcium hoses from the doser because i dont want it to get out of balance until the next night or the night after until it drops back to 8. The calcium probably does fluctuate, but it would only be 4ppm so it's kind of hard to measure that on a daily basis.
