how to handle calcium precipitation

[sukisuki1]

I have decided that I do have calcium precipitation. Will this cloudiness go away on it's own or do I need to do something? Will it hurt my corals and clean up crew? I have searched this site for an answer and I am not finding much. Thanks!

Do a water change. That will usually instantly eliminate the cause of the precipitation providing there's nothing wrong with your salt.
Then test Alkalinity, Calcium, and Magnesium to find the cause.

if you have precipitating you calcium and alk are WAY too high.. probably over 750 ont he calcium side which will cayse a "snow storm"

Usually the pH will be really high also. Precipitation will morely occur when the pH is on the high side.
