Alk of 11 is a bit high. Might be higher than it is used too.
I'd give it some time to adjust.

I use reef crystals it's known to have high dkh and magnesium and also I need help on how to mantain my parameters and keep a more stable tank

I use instant ocean and use Kent marine trace elements every water change
