Calcium alk issue

[cam08]

My calcium is low and my alkalinity is high. Dont know how to fix this issue. Will using 2 part dose help? Using instant ocean salt. Will change to reef crystal but not sure if it will solve the issue im having.
Calcium-365ppm
alk-11.9

Reef crystals will have even higher alk.

Dose the Ca part of a two-part, like you suggested. Let alk come down on it's own, or do a water change with lower alk salt.

What is your Magnesium at? Bump this up to the proper level if you have to. After that you might have to adjust your Calcium a little too. While your Alkalinity is a little high, it might be able to work once you get the other two lined up.

You can bump up cal but I wouldn't worry about the alk..
