Ph problems

[brownjoshua475]

So I'm having ph problems in my reef tank I just my ph on the hanna checker and it's at 7.6 I know this ain't good. I just started dosing kalkwasser in my ato to get steady alk and calcium parameters. My dkh is 8.3 and calcium 420 I thought kalwasser was suppose to raise ph. I'm not sure what's going on. How can I get my ph back up

How are you testing for pH? Calibrated probe?
How do your corals look?

Ya the hanna checker is a calibrated probe and corals actually look fine all the polyps are out on the stony corals
