Do you have a magnesium reading? Magnesium, Alk, and calc are all interconnected.

There are a few options to take a look at but mag is the third measurement that is needed. When I get to a pc I can give you a few links to sites that helped me out with my recent troubles.

In any case this article gives some great information on the topic.

This is what I used to help get my parameters in check.

With large water changes every other day, it is hard to believe those parameters aren't where they need to be unless there is an issue with the salt mix. What is in the tank is no where near needing dosing of any kind...that is minimal stock for a 30 gallon tank, let alone a 75! What tests are you using? It is important to have things in check, but it is also important to understand that chasing numbers will cause you issues. I tried chasing the ph I want in my tank, but can never get it. I have no issues and things thrive so I stopped.
