Well, backed off a little (to maybe 180 ml per day), left things for a couple of days.
Parameters are bloody awful. Salifert tests show under 400 calcium and under 8 alk. Went to my local lfs, and their red sea tests showed 350 and around 7. I know that's not catastrophic, but after a gallon each of 2 part in 2 weeks, it seems stupid low.
Any ideas what could be causing such massive precipitation in a new tank? Is there a possibility of stray voltage forcing calcium out of solution? Did the dust from the sand (which I did rinse, but there is always some) provide an ideal "seed" environment?
I'm open to any ideas before "massive water change weekend" kicks in.
