We've been dosing our 12gal. nano cube for the past week and a half. We've effectively raised our Ca level to 300 last time we tested. Roughly 4 - 5 days ago. Today, however, we tested again, before the water change, and our Ca was only 220.
We dose each day, religiously using exactly as much as it says we need to for a tank that size. Is there any reason we're having difficulty raising our Ca level, or why it would change much?
Our substrate is a crushed coral, not an arganite sand bed.
We've got one small hammer coral, two tiny zoo's and one xenia. They've all showed progressive growth, but I find it odd that they'll continue to grow even when our Ca level is so low.
Also, I realize they're using some of the Ca in the water, but still, why would there be such a significant drop if we dose daily at roughly the exact time per day?
