    What's your mag and alk levels? How big is your tank and what test kit you using?

    Strange that it's not going up, I was thinking mag could possibly be low causing the calcium to precipitate out but probably not the case. I see what may be the reason now I've re-read the question,
    Assuming your buffer powder is similar to the Red Sea buffer I use, 1g will raise calcium by 3.6 ppm in 100. Litres, or in your case
    1mg will raise calcium by 0.0036ppm x 30 (your daily dose) raises calcium by 0.108 per day in 100 litres, you have 400 litres so 0.108/4 is raising calcium in your tank by only 0.027 per day,
    Chances are your tank is using that each day anyway, so despite dosing it's all staying equal,
    Hope that all makes sense, and I'm more than happy for someone to double check my sums.
    Nice tank by the way,,

    Your mg could be higher, up to 1500ppm is ok. Looking at your photo I don't see a lot in there that will be using your calcium and carbonate. To me it looks like a predominantly soft coral tank. That being said it is a good idea to try to match nsw as near as possible. IMO your dKh is to high should be 7.7 for softies.
