Low ALK and Kalk?

[footbag]

I'm considering adding a kalk drip to my nano setup. My ALK seems like its continuously dropping. If I don't add buffer at least once a week, it drops to around 6. If I get up to around 10 with buffer, and begin a kalk drip should it also maintain ALK. Or will I still have to do the same number buffer additions? My Calcium is at 440 and I'm using Oceanic salt.

Is your Calcium dropping at the same rate as your ALK?
It would be worthwhile to test you Magnesium now too.

I was thinking that may be the problem, but what depleats magnesium? A few water changes will fix that right?

Usually regular water changes will fix magnesium because under normal conditions it's used up very slowly.
Calcium Carbonate precipitation depletes Magnesium.
