Carbonic hardness (alkalinity) should range between 7.5 and 11.0 DKH (8-10 is better) so you are fine.

I read it in the API reef master test kit. What it says is natural seawater has a carbonate hardness level of 5-7 dkh.

My bad I just read the next page(witch is in french except the first paragraph) and it says 8-12 dkh

According to what I know and read, it should be from 8-12 dkh. To check ALK.DKH, I suggest using Salifret, it is more precise.
