Have a look at this, it might help you. What is your magnesium at? As well as KH?

I had problems too getting my Ca levels up. Combination of water changes (using IO and every time I changed the water was causing a drop due low Ca) and low Mg (again IO).

Now find if making up the batch of new SW, add Ca and Mg to the mix before the water change, my reactor easily keeps up the Ca and very, very rarely do I need to add Mg to the display

the calcium level is always down.

down to what value? This is fish only, correct? What would you like Ca to be?
