    So I have been testing my parameters every week lately. Just watching
    to see how everything is doing. Here is the past 4 weeks my Cal has
    dropped from about 500 to 360, and my Mag has dropped from 1350 to 1200.
    I also have noticed that my pH has been staying above 8.0 when it
    normally stays about 7.8, and ALK has been staying at about 9. Not really sure if this is something I should
    be concerned about or not. I have been adding some kalk water the
    past week, but it only been 3 times and in small amounts.  I am getting some MAG and CAL added to bring them back up

    For every 1 meq/l of alk your coral consume they will also consume about 20 ppm of calcium. That ratio is linear so I am thinking your tests are a little off. Are you doing weekly water changes? I would think a water change should bump your CA up pretty quick.

    I like to add a little Tech-M Mg to my water change water to keep that in check.

    I have also given up on 2 part and just top off with limewater, it's so much easier and things are basically just as stable.
