Can't get my calcium to go up

[brad23]

It's stuck at 370 for the last 6 weeks. I just added some SPS frags so this really needs to come up.

I'm using Randys two part and was adding a 100ml a day of both. Should I increase the amount I'm puttting in? i don't know what else to do.

I test it in the day time, at night it seems to be higher.

It's a 75g with a 30g sump. My DKH is around 10

I'd use more of the calcium part for a day or two, not more of both, as the alkalinity is fine. This calculator shows how much to use:

Hoe much more? I'm already putting 100ml in a day

The calculator shows how much to use to boost the calcium from 370 to 420 ppm or so. Add that in addition to your normal amount.
