one more question how do you adj it
Thats the 635 million dollar question. Many different options, mostly depending on your budget, and whether you want to dose with a measuring spoon or eyedropper each day.
https://www.saltwaterfish.com/site_11...ot_parent_id=6 <--CaribSea Purple Up is supposed to be pretty good and seems to get really good reviews. But thats mostly to raise calcium.
You didn't give a whole lot of info in your first post, but how long has your tank been running? Coralline takes a while to get a foothold, quite a bit longer than the messy undesirable algaes.
To raise both calcium and alk at the same time, you could dose with mixed kalkwasser, via your FW topoffs, best used at night if possible to balance PH swings.
2 part Alk/Calc products are pretty easy to use, but in my experience are best used to maintain rather than raise.
