Dkh of 8 is perfect. I would not call it low, its actually a big higher than the ocean.

i agree...the trend these days, is that more aquarists actually keep their systems at a lower dkh around 7.5-8.5 . i think its fine
8 dkh is ok. I prefer 9/ 10 in my system. keeping it steady is the issue.
What salt mix are you using? The water change may have reduced it.
Alternatively, as corals and coraline grow they consume alkalinity faster than calcium in the biotic precipitation of calcium carbonate. For every 20ppm of calcium used in this process, 1 meq/l (2.8dkh) of alkalinity is consumed. You can boost it with baking soda.
The sticky thread in the reef chemistry forum regarding salt mixes and their content and the reef chemistry calculator may be of interest.
