What can cause an alk swing? I've been on top of my parameters lately. They don't really fall very quickly. Maybe over the course of a few days my alk would drop by .1 or .2. However at my last test it dropped around .8 over 3 days. What can cause a variance? No new corals were added. Also had a sudden drop in nitrate over this time. Went from steady 15 or so down to 3.
