Why is my alk so high??

[livinlifeinBKK]

Not complaining, just curious why my alk is so high...(it hangs around 11-12). This tank is about 4 months old and is very lightly stocked with only several inverts and no corals yet except for a black sun coral who seems to be doing great. I just don't understand how my alk can be so high when the salt I use (Red Sea blue bucket and for the past couple weeks AF Reef salt) mixes to alk levels of around 8-9...it's a nano tank and parameters are stable but I'd like to understand why this is so I can better understand what's going to be going on when I start adding corals. Anybody have any insight to share?

Have you tried checking your batch number under the lid of the bucket with the Red Sea batch checker https://www.redseafish.com/mybatch/
