Alk confusion Help

[24storm]

I am looking for help with some test readings i am getting.
I am using Elos test kits

Alk 15dkh Elos test kit 15 drops tried 2 different test kits
Cause i think this is to high.
Calcium 450 Elos test kit
I have turned down my reactor just a little to get it down
PH 8.1- 8.2

Should the Alk be that high?

How do i get down?

The tank seems happy and the DKH has been this high for a while now

Using Reef Crystals

Thanks Keith
