Calcium percipitation

[ebqwert]

How do I know if I have created a problem with too much calcium?
Here’s what’s happening:
90 Gal tank set up in July 135 lbs of LR
After a month when cycle was finished started dosing with ESV B-ionic, Equal parts of Alk and Calc.
Calc started at 350 and is now around 375m but I can’t get it over 400.
About a month ago I added a sump (29gal tank ½ partitioned with 65lbs LS and Aragonite.
During the past 3+ weeks I’ve noticed very fine white particles floating in the take. Lots of them, they make the take almost look cloudy.
Any suggestions would be really helpful!

If it was a calcium related problem, you would see a cloud and not particles.
I would first suspect your sand bed being disturbed. Maybe a crab or fish moving it..
