Raising Calcium in Nano Tanks

[appaloosa1224]

I've been trying to raise the calcium levels in my two tanks for about a month now with almost zero progress. I've been using Brightwell's Reef Code A+B to try and raise it. My levels in both tanks (20 and 25g) run somewhere between 380-420 (using an API test for daily checks, and Red Sea 1-2 days per week). Alkalinity is hanging around 8-9, pH is 8.4. I've been adding the two part at a higher rate than the 'base' dosage and definitely not getting anywhere with it. Any suggestions? I use the Red Sea Salt which I've enjoyed using, but it mixes on the lower end of these parameters as well, so switching salts is a consideration. Or maybe I should just stop worrying about it!

What is your magnesium level?

Otherwise, those numbers aren’t bad.

What is your goal & why?

I find it hard to raise levels in my nano because I do water changes so frequently. I use Kalkwasser in my ATO to help maintain levels similar to what my salt mix contains.

What is your magnesium level?

Low, sitting at 1120 right now. Just did the Red Sea test to check, and it's lower than normal actually.

I've just found my LPS tend to be a little happier if I can keep it above the 400 mark. Sitting at home and having all this time to stare at the tanks has me testing a lot more and noticing these things.
