You are still cycling, I'd stop dosing the kalk like stated before. Read the article that was linked for sure.
Your ph is high, but not outrageous.....but stop dosing anything at all for now....HTH Wait till you NEED lot's of Calcium then start testing Ca, Mg, Alk.
If you haven't read or heard it before....but "nothing good happens fast in this hobby, only bad things happen fast".
You are also going to need a lot more LR if you want to go Reef w/ this tank.....Start reading and don't stop cuz there is always something to learn in this hobby.
Good luck.
